> Matt: In the case of planets, if there's literally an uncountable number of stars that can have planets, then it is mathematically certain that *somewhere* in the universe there will exist a planet like ours. I don't even flinch at that. I flinch at *any* speculation about life itself. There's a ton of questions to answer.-That's the part that bothers me.

> Matt: Consider the evolution of eusociality... we know of 15 species that exist that have ever evolved this trait. (It's the precursor to living in organized societies.)

> Using a thought process like that, It might not be unreasonable to posit that life could be rare enough that it only happens in 1 out of every 10 galaxies. (And at those distances... why bother looking?)-Bacteria don't need eusociality, so I don't follow your reasoning to get to 1 in 10 galaxies
