Asteroid attack 2 - Where's the evidence? What Really Killed the Dinosaurs? BBC Science

Scientists believe a massive asteroid is the most likely explanation for the extinction of the dinosaurs. However, if an asteroid did wipe out all species of dinosaur there should be a 200 km crater somewhere on the planet. Scientists hunt for this asteroid evidence in this video from BBC show 'What Really Killed the Dinosaurs?'.

I want to hear an explanation as to how all these gigantic creatures were able to get as big as they did, and why the fact that they couldn't possibly exist now [because the gravity we experience today simply will not allow it] is not discussed.

@maxxout90 when you split an atom with your bible then we can talk. till then go fantasize about your fairy tale somewhere else.

@maxxout90 first of all learn how to spell and speak English correctly. And second, please get an education. the bible is a story book it is not fact or science. and you dont need a flood to cover up bones. it gets covered up in many other ways like wind, rain, lava, etc.

"Noah's flood"?? Seriously??

That has to be the most ignorant, yet serious(?), answer possible I think.

Sorry, friend, but no. "Noah's flood" has long been proven to be fiction.

And, despite your desire to make your belief system fit reality, all dinosaurs were extinct ~millions~ of years ago. If you wish to debate matters such as this I suggest you acquire an accredited education with an open(ed) mind first.

~Peace~

@johnthreesixteen316 Creationist coming to proper scientific videos. isnt that just dandy? What happened with the rapture 2 days ago? I thought all you religious cooks would disappear!

[johnthreesixteen316]

@MrPoopybum Hello friend. The fossil record shows that many creatures were much larger than those of today......dragonflies with 4 foot wing spans. Giant sloths 20 feet tall etc. All found in the fossil record. The thing you have to ask yourself is this.....where do we find the fossil record including all of the dinosaur remains? A: In water deposited sediments. Noah's flood killed them all 4400 years ago.

@maxxout90: Exactly and that's why scientists strive to learn the other billions of grain out there. How can we even be sure that the bible itself is correct? It was written by man, was it not? The fact is that we cannot even comprehend the magnificence that God has bestowed upon us. Unlike religious zealots, science is at least TRYING to comprehend His works. Perhaps one day, our descendants will laugh at us for believing in evolution and Big Bang but theirs is a work learned from our mistakes.
