The earth is only about ten thousand years old, whoever disagrees with that are going to hell when they die. Don't you just love religion?
I wonder how it would've been without the asteroid. Would dinos have developed intelligence? Would earth now be populated by smart reptilians? Who knows?
I love how they put together all of the clues from around the world to understand how, when and why the dinosaurs went extinct. It's amazing, thank God for smart people!!
The dinosaurs died in the biblical flood…. Geology proves it. Carbon dating is worthless & inaccurate. The theory of evolution is a lie & fails scientifically. COUNTLESS scientists concur. You must do your own research. Start with "Genesis Paradise Lost." The world was created & is not some result of a chaotic event.
Are there still people believing in Dinos?
What was the role of the asteroid to our existence ? Am reading some of the comments they appreciate it , maybe i missed its vital role.
Evolution went wrong. Intelligent design came to correct it.
Iridium…
Incredibile interesting facts about congratulations for welcome
Now scientists and archeologists think there was 2 at the same time, one big one smaller……. YIPE !
Very interesting episode
These things lived over one hundred millions years ago but humans only been around for a couple thousand years
1still remains, The Croc 🐊
The scientific story way greater and way deeper than the religious one at least to me !
you scientists did not know how the dinosaurs died ?
let me tell you this they died from the flood of Naoh !
Tnx to asteroid)) But how humans appeared?
Majestic moment 31:38
Its all speculation ..if you look closely and examine all evidence with a sensical fore thought. You will also conclude it is all a ploy to discredit GOD.
Dont believe the lies of a condemned world.
Liquifaction. ..deposits all sediments according to density . It happened very fast.
lol a lot of religious nuts in the comments
I could show you the exact impact and and aftermath of the impact
I am sure you can tell a lot about the past from the sentiment layers but what if your timeline is wrong I think this whole thing is wrong
The other thing that may have happened is that it hit in the you could have peninsula and exited in the Drake passage going right through the planet maybe smaller and more pointed would be an incredible impact that tsunami that they discussed was secondary to a land wave much like when you whip your sheet on your bed and the wave goes through it travels all the way the end but it was with the land followed by water does evidence all through the northern hemisphere you can see where the waved ended look at Google Earth it's amazing what you can see there
I would love to talk to this scientist
I think it has happened a few times and the crater they are looking for is in the drake passage between south America and Antarctica and it created a whole lot more change than anyone seems to realize I talked to a scientist from a NASA site he says that the 500 mile wide circle between Antarctica and South America is from plate tectonics I said not a chance not only is there a crater but there's a 1,200 mile long trench with a big hill at the end from the impact that's one of two theories there either that's an exit wound or an entrance wound but either way is split Antarctica off of South America and Australia off of Antarctica created a wave of land the one all way past the North Pole it's it's fun Antarctica in Australia a circle towards the South or Antarctica ended up where it's at and Australia you broke off and kept going following that land wave was a water or giant water wave that sent a the blanket in Antarctica in the in the new Sub-Zero location which flash froze the warm water it's sent to wave up towards Africa mud hot mud that traveled all the way across Africa and ended up depositing it s sand that was left as a Sahara desert and the Middle East and over India well parts of the kept going on a the green linen it covered Asia in a lot of sand but it covered South America in hot mud which is why everything in the world is buried right now and I don't think it was as long ago as they think either way just take a look at Google Earth and imagine write the Drake passage you can measure the 500 mi greater and then let physics follow you from there create a giant wave of the crust they ended up in places like Mariana's trench you can see the end of the wave also the northern hemisphere the land wave that is
Disregard local possible volcanoes, floods which does the same thing an asteroid so-called would do on massive scale, intense rains, river recourse etc…
This geologist aren’t searching for the truth, they’re searching for their religious faith based theory.
How about a whole world wide flood with waters retractions forming canyons and sediments…?
That would perfectly go hand in hand with human hieroglyphs found in hieroglyphs all over the earth showing even human coexistence with dinosaurs.
But if the Smithsonian institute would go to such extents of destroying evidence that is not fitting with their theory, think about it, are we living in a made up world where the more aggressive get to write their version of history based on their faith in their vague theory? You age the earth based on radiology? Use chicken poop on any wooden surface, it’d get you same carbon dating they use to tell how old a man made wood sculpture is. Ridiculous. This people went unquestioned all this centuries.
Two-thirds? 66.6%? I thought it was more like 80% covered by water
What size nuclear bombs?
Amazing and interesting
You don’t really know how we came to be. God made us believe it or not.
Evolution doesn’t work out the way you think. No one can say what really happened. Where did man come from
Asteroids= loitering munitions of ET
“Without the Asteroid, there’d be no Us!” Wow – that hit hard!
Yall never read the Bible
Sad
OK Then but that's just one Period of time what about the other two Time Periods ? All these experts are wrong he forgot to mention about the other periods of time which are 3 Jurassic and the Triassic and Cretaceous!
were not from primates
They didn't have a chance.
Legend has it that the meteor was really chuck norris arriving to earth 🌍
Hello I am lawi from Kenya,Africa I really like ua documentary,could I have found one of this earth layer that can be read from the great rift valley,watch my attachment.
So the scientists treated Alvarez like Egyptologists and paleontologists currently treat ppl like Graham Hancock and Randall Carlson.
The cult of the main stream refusing any evidence that contradicts the dogma of the currently accepted vernacular. Like ended the age of Dinos, Clovis first, the population of the Americas, the disappearance of virtually all large ice age mega-predators from North America, the water erosion damage on the Sphinx, etc…..and the fact that if you investigate these things, put forth evidence, and make any reasonable assumptions, backed by multiple threads of evidence, that goes out of sync with the mainstream you will be tormented, ostracized, and likely struggle to get research funding until the end of your days.
I thought that was a cat in the thumbnail
You can actually faintly see the crater on google maps, pretty cool.
Fascinating and such an important subject
Dinosaurs never existed
I've been talking to Elon musk about running asteroids into Mars with satellites if they have water or precious metals based on the theory of intelligent design that could have been done to put important things humans would need on Earth. Don't get cremated if you want to be reanimated by God at some point he needs the DNA in your bones to reanimate you. And you're put six feet under and in a solid casket so that if a demon takes over your dead body it's not going anywhere. It is likely that small asteroids with necessary elements and water hit the Earth but didn't cause an Extinction because of intelligent design
That high energy impact evidence could be from a previous world.
What if our world was formed from pieces of other worlds that had life and the dinosaur bones are left over from a previous world that is now part of ours. If a planet that had dinosaurs exploded and part of the mass hit what is now Earth than those dinosaur bones would be from a previous world and then God recreated them with the genetics left in their bones here on Earth💥
There was no asteroid that killed the dinosaurs. You can't go extinct and then evolve into birds they were transformed into birds so that they could fit on Noah's ark and the ones that were way too big we're given gills and sent to the ocean. Evolution can and does happen but not in this case but the evolution is normally merely an adaptation and it doesn't take millions of years it took one century for elephants to drop down to where only one in four has ivory tusks because they were being killed for it that is an adaptation but it's also evolution
