It is estimated that the first life on earth survived asteroid impacts to earth between 3.8 and 4.4 billion years that were up to one million times more energetic than the chixalube impact which killed the dinosaurs 64 million years ago.
to put that kind of impact in perspective, it is estimated the fireball from such an impact briefly made the earth the brightest object in the solar system, outshining the sun by an order of magnitude and made the earth visible to the naked eye from a hundred light years away.
