Do we know what the Earth was like prior to the asteroid collision that formed the Moon?  Could complex life have lived here?

I've read the Earth was still molten, but I don't know if that's the popular consensus or more of a guess.  I was wondering how likely it would have been for complex life to have lived here pre-Moon before getting being wiped out by the asteroid.

It's highly unlikely that there was life. The collision happed several hundred million years after the solar system formed. The Earth, at that point, couldn't have supported life.

Also it wasn't an asteroid that hit the Earth, it was a planet the size of Mars.
