The fact that life appeared on earth very shortly after it formed gives us a good indicator that Abiogenesis may not be that rare.

Something that's probably a lot more rare is favorable conditions over a long time period. It took a long time for life on planet earth to evolve into more complex forms.

I'm pretty sure we're not the only ones out there. But will mankind and our space neighbours exist long enough to facilitate communication?

Is every species that is competitive enough to subdue all other life on its planet doomed to disintegrate due to internal conflict?
