Dinosaur impact theory changed

Okay, I'll buy the idea that climate change could have killed many of them due to a natural disaster such as the astroid theory etc.

I know the leading idea is we didn't exist at the same time as the dinasaurs, but I always thought if we did what would we do? Maybe kill them before they kill us. Or if you subscribe to the idea that we came here from somewhere else, maybe we killed them off when we got here to make room for ourselves.

the problem is we may nvr know the complete truth as to what happened.

It may have been a world wide disaster after a astroid hit or it could have been just been catastrophic climate changes...we dont know.

all we can do is look at the cold hard facts and make our own descisions up with facts and theories.
