00:00 This comfortable home with a magnificent view of the Mediterranean sea will be a perfect shelter against the rain.

00:07 This is what a real estate ad for the Neanderthal man could have looked like 100,000 years ago.

00:12 Today you will discover wonderful and strange caves in which you could live. Or not.

00:17 Of course, at the time, neither real estate nor advertising had yet been invented.

00:22 Not to mention the fact that the Neanderthals did not know how to build houses and often lived in caves.

00:28 However, one of these caves looks a lot like a residential building.

00:32 It is located inside a high limestone monolith known as the Gibraltar Rock.

00:38 If the Neanderthals had an economy, the caves inside this rock would certainly have cost a fortune.

00:45 The sailors discovered it in 1907, simply by noticing a large hole inside the imposing rock.

00:52 For many years, scientists have studied this place and found traces of Neanderthals.

00:58 They discovered ancient tools in the cave, as well as animal bones.

01:02 But the coolest thing is that they found no less than four caves inside the rock.

01:08 It was like a small residential complex.

01:10 The Neanderthals lived next door to their neighbors and helped each other in hunting and fishing.

01:15 They decorated their feathered homes and drew abstract shapes on the walls.

01:20 Imagine that these ancient hominids spent their time in these caves 100,000 years ago.

01:25 And now, it is the scientists who spend all their time studying in detail the life of the Neanderthal man.

01:31 At the end of 2021, archaeologists discovered a hole opening into a tunnel inside one of the caves.

01:38 They slipped into this opening and cleared a space, until then unknown, under the ceiling of the cave.

01:44 This place has been inaccessible for more than 40,000 years.

01:47 And it seems that this summer, it is one of the most prestigious apartments in the entire complex of the mountain.

01:52 It has high ceilings covered with ancient stalactites.

01:56 Crumbled stone curtains divided the apartment into several rooms.

02:00 These scientists have also found remains of animals, as well as marks of claws on the walls.

02:05 It seems that the Neanderthals never lived here, but they were used to visiting this place.

02:11 Archaeologists have also found the shell of a sea snail called Nussela lapillus, or Atlantic porpoise.

02:18 A Neanderthal would have brought it to this place for a reason that we do not know.

02:22 But the main owners of this place are hyenas.

02:26 These caves show that the Neanderthals were closer to humans than monkeys.

02:31 They had a way of life and even some of their own customs.

02:34 There is still a lot of work to be done, and scientists hope to make new discoveries inside this rock.

02:40 In the meantime, in 2003, archaeologists discovered another ancient habitation on the island of Flores, Indonesia.

02:47 At the heart of the green jungle, they found a cave housing ancient tools.

02:52 At first, everyone thought that our human ancestors had lived here.

02:56 But shortly after, scientists came across a strange adult skeleton.

03:01 A deep analysis showed that the skeleton belonged to a 30-year-old woman measuring 1 meter,

03:07 which is just a little more than half an average adult.

03:11 The weight of the woman was equal to that of a German adult shepherd.

03:15 The skeleton did not belong to the Neanderthals or the Australopithecines.

03:19 It was a new unknown species that scientists named Homo floresiensis and nicknamed the Hobbit.

03:27 There were also remains of ancient animals never seen in the cave.

03:31 There was an elephant the size of a cow, large goats and giant rats.

03:36 Archaeologists discovered that the Hobbits were not the owners of this place.

03:40 The main inhabitants were big cats like rats.

03:44 They may have fought like the Hobbits elsewhere.

03:47 Analyses have shown that Homo floresiensis was not our direct ancestor.

03:52 It is part of a distinct branch of evolution.

03:55 The Hobbit skeleton looks more like a monkey's than a modern human's.

04:00 In 2009, in the luxurious jungle of Vietnam, archaeologists discovered the Hang Son Dung cave, the largest in the world.

04:08 If you enter this cave and you scream, you will hear your echo for a long time.

04:15 In some places, the height of this cave reaches half the height of the Empire State Building.

04:21 And its total surface is larger than a house in the center of New York.

04:26 Hang Son Dung is one of the three caves of the Vietnamese jungle.

04:30 Many labyrinths connect these caves.

04:32 Inside, you can find plants and unique trees that live completely cut off from the outside world.

04:38 It is a real underground jungle.

04:40 In some places, there are collapsed ceilings that let in the sunlight.

04:45 In addition to the unusual flora, you will see very old stalactites.

04:49 Some limestone deposits are more than 450 million years old.

04:54 They were there even before the appearance of dinosaurs.

04:57 There are also many rivers in the cave.

04:59 The rainwater that falls through the holes in the ceilings formed them over the centuries.

05:04 These fast streams look like the toboggan of an aquatic park.

05:07 They lead to underground labyrinths that no one has ever seen.

05:11 Scientists have studied only a small part of all these caves.

05:15 The next cave, also one of the strangest, is located in New Zealand.

05:19 Hundreds of thousands of bats live inside.

05:22 Each of them shines with a blue light.

05:25 Together, they illuminate the cave.

05:27 You may feel like you are on another planet, but you will not be able to stay for very long.

05:33 There are devices everywhere to measure the air.

05:35 Scientists make sure not to exceed the level of carbon dioxide necessary for the existence of bats.

05:41 These insects are very sensitive to the environment.

05:44 If there are too many people in the cave, or if people stay too long,

05:48 the park staff will ask them to leave the place.

05:51 It's like stealing the oxygen from bats.

05:54 We have seen some rather surprising caves.

05:57 But what would you say about a scary cave?

06:00 We are going to the desert of the province of Almara, in Yemen.

06:04 What we are looking for is not a cave.

06:06 It's just a black hole in the ground, in the middle of the desert.

06:10 It is as big as a basketball court.

06:13 It's not its size that's scary, to be honest, but what's inside.

06:17 Scientists are still not sure what it is.

06:20 From the depths of this black hole, a disgusting smell of rotten eggs is constantly coming out.

06:26 And sometimes, you can hear strange and terrifying sounds.

06:30 The darkness of the giant hole in Yemen absorbs all the sun's rays.

06:37 So you will not see what it can have inside, even with a powerful flashlight.

06:42 People have flown over this place in helicopters.

06:45 They filmed it with drones and powerful lenses, but they were unable to immortalize anything, except for total darkness.

06:52 You have just arrived at your favorite place on a deserted beach.

06:55 It's so quiet here that you start to sigh.

06:58 But when you open your eyes, it's a shock.

07:01 But what's going on? Is this a real house that has just appeared on the shore?

07:06 It looks a bit like the beginning of a science fiction novel.

07:10 But not if you live near this beach in El Salvador.

07:13 There is an abandoned house that seems to have been mysteriously rejected by the waves.

07:18 How did this villa get there?

07:21 And how did no one notice it until now?

07:24 This enigmatic building is located 60 km south of San Salvador, the capital of El Salvador.

07:31 Residents say that the house was once a hotel, named Puerto Ventura.

07:36 At the time of its construction, its main attraction was the fact that it was really very close to the sea.

07:41 Unfortunately, the contractors had to make some mistakes.

07:45 One reason for this is that it was not necessary to have an official building permit.

07:50 The hotel was too close to the water and dangerously exposed to elements.

07:54 This Roman-style villa is now only 15 meters from the shore when the tide is low.

08:02 You can only access it in the morning.

08:04 Because later in the day, the tides completely fill the ground floor with salty water.

08:08 This two-story hotel is now nothing more than a ruin.

08:13 Its facade is very impressive with its Roman-style pillars.

08:17 It also has large windows on the second floor.

08:20 You can still see parts of the metal structure, as well as what remains of the second floor entrance door.

08:28 There are steps at the top of the building. Tourists sometimes come to sit there.

08:33 More and more people travel the area to take pictures.

08:37 Even if climbing the house is a bit dangerous.

08:40 We don't know how long it's been where it is today.

08:45 But some of the inhabitants say it's been at least 20 years.

08:49 Most people ignored its existence until it was discovered by a TikTok user in 2021.

08:55 But that doesn't answer the question.

08:58 How did the hotel end up in this place?

09:01 This is where things get a little blurry.

09:04 While some inhabitants claim that the building was abandoned decades ago,

09:09 others claim that it was deserted after Hurricane Mitch passed in the region in 1998.

09:14 Hurricane Mitch was one of the most violent meteorological phenomena ever recorded in Central America.

09:19 During the storm, the winds blew at a speed of 290 km/h.

09:24 And the hurricane lasted about 15 hours.

09:27 It also caused huge downpours.

09:30 And then there were floods and many landslides.

09:34 Being built so close to the coast, the old hotel had little chance of resisting these extreme weather conditions.

09:42 And it was literally drained.

09:45 After a moment spent under the scorching sun, you may dream of snowballs thrown on the shore.

09:51 You know, to lower the temperature a bit.

09:54 I'm not kidding.

09:55 This strange natural phenomenon did indeed occur in 2016.

09:59 An 18 km long stretch along the Gulf of Lobe coast in western Siberia was covered by huge snowballs.

10:07 Because of the low temperatures, small pieces of ice began to form in the water.

10:12 Then the wind and the waves rolled them and transformed them into gigantic snowballs.

10:16 Some of them were the size of tennis balls, but others were up to 1 meter wide.

10:22 In 2012, a 2004 Harley Davidson Night Train arrived on the coast of a British Columbia beach.

10:29 It had been carefully placed inside a container.

10:34 It took time, but we finally found its owner.

10:37 His name was Ikuo Yokoyama.

10:39 And he had lost his motorcycle after the tsunami that hit Japan on March 11, 2011.

10:46 To reach its final destination, this Harley Davidson traveled more than 6,500 km.

10:52 To celebrate his trip and his arrival, Yokoyama donated his motorcycle to the Harley Davidson Museum in Milwaukee.

10:58 It has been exhibited there since…

11:00 "Sometimes you'd like to see it."

11:02 This strange phenomenon will give you the impression that someone has spilled dishwashing liquid on the beach.

11:07 But this often happens in Queensland.

11:10 The sea foam completely covers the shore several times a year.

11:14 This happens mainly after a storm, when the waves of the ocean move the dissolved organic matter into the water.

11:20 Basically, it's like a giant ice machine.

11:22 After the Ebby cyclone in March 2017, some beaches had to be closed due to the huge amounts of white foam.

11:30 The wind even carried some of this foam into the neighboring cities, making the inhabitants believe that it was snowing.

11:37 Would you be surprised to see a 2 meters by 2 metal rusted dike fall on the beach of Tonpatelin?

11:44 Because in 2017, the inhabitants of Coeur d'Haleine, in Lidao, certainly were.

11:49 It turns out that it was an old storage tank.

11:52 Someone had decided to embellish it a bit by adding white spots to make it look like a dike.
