Default Ancient asteroids kept on coming

Quote:
The evidence is in the hollow-eyed face of the man in the Moon: a wave of asteroids showered Earth and the Moon in the distant past. They scarred the lunar surface with vast, circular impact basins and wreaked even greater havoc on this planet, which presented a bigger target. Now, a pair of studies published in Nature1, 2 suggests that the battering lasted much longer than was thought, spanning nearly the entire first half of Earth’s history. The results imply that a prolonged succession of impacts — some of them large enough to vaporize oceans — could have shaped the early evolution of life.

Might also explain why it took so long for complex multi-cellular life to get started.

Stevie, how can you possibly imagine that some fundie/creo will fit this kind of catastrophic bombardment with their early-Iron Age myths?

I mean, come on dude, these people have standards!

Right?

Hello?

That was either very deep, or very shallow. I think I know which, but I might be wrong.
