I get a big surprise, the life of earth was so long time.
from the webside,it's tell "from earth formation out of the gas and dust of interstellar space, which culminated some 5 billion years ago, right up to the present."

They said "Humans? They don't appear until 100,000 years ago."
I didn't belive it. The timeline was so long ,but the time of Humans is very short.
I didn't know why?
