"What If We Have Completely Misunderstood Our Place in the Universe ? A Harvard astronomer has a provocative hunch about what happened after the Big Bang. Our universe is about 13 billion years old, and for roughly 3.5 billion of those years, life has been wriggling all over our planet. But what was going on in the universe before that time ? It's possible that there was a period shortly after the Big Bang when the entire universe was teeming with life. Harvard astronomer Avi Loeb calls this period the 'habitable epoch,' and he believes that its existence changes how humans should understand our place in the cosmos. The full article is here"

I was wondering about this too. He also gives an estimate of about 1 million years for these simple lifeforms (he suggests possibly algae) to evolve before having their planet's environment devastated by global change. Life on Earth took A LOT longer than 1 million years to develop into much of anything, let alone algae (even if life was seeded by asteroids, 1 millions years isn't very long to develop into anything).
