snake ，lion，or other......

Answer 1

Refugees from Atlantis (Native Americans) arrived in the Americas.

End of the Ice Age.

Answer 3

The mega fauna died out.  Mammoths, sabre tooth tigers and a whole lot of others.

Possibly caused by climate change, possibly caused by recently arrived humans hunting.  Probably a bit of both.

Answer 4

Probably nothing happened 10,000 years ago.   It has only been about 6,000 years ago that God created the Earth; so, it's pretty much impossible that anything could have possibly happened before that.
