Planet postion in a solar system seems to be up to chance. Is Earth lucky or made special?

I don't even flinch at that. I flinch at *any* speculation about life itself. There's a ton of questions to answer. -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?)

\"It is, brahmin, because of attachment to views, adherence to views, fixation on views, addiction to views, obsession with views, holding firmly to views that ascetics fight with ascetics.\"
