Supernova Left Its Mark In Ancient Bacteria

> life might be quite rare...
and...
> life is much more resilient...

I'm going to split the difference between you two. I just finished reading John Gribbin's "Alone In The Universe: Why Our Planet Is Unique." Yes, it's another rehash of the "Rare Earth" hypothesis, but he bases it on some of the latest computer simulations.

Gribbin says that *simple single-celled life* might be very common throughout our Galaxy. But Gribbin makes the argument that *sentient* life is probably quite rare.

You may not agree with his conclusion, but he presents the latest evidence and theories for solar system formation. Well worth the read.
