This makes the Fermi paradox even weirder: If there is a bunch of these asteroids floating around in space, ready to seed life on numerous Earth-like planets, there should be an even bigger chance of seeing someone else, than if life have to originate on the planets themselves.

It could be life is evolved elsewhere but it's hard to communicate / travel many light years?

Cool. It's interesting to get new info on how it kicked off.
