    However, in the universe’s life of billions of years, many civilizations may have risen and fallen, just not at the same time. Maybe life is such a rare confluence of events, that it only springs up occasionally, and never at the same time.

      Again, who said anything about “civilization?” Even just on Earth, life has existed for 4 billion years. That’s 4 billion of the 14 billion years the universe as a whole has existed, or 28% of the time, which I wouldn’t call “rare” at all!

      Life on Earth started damn near immediately as soon as the crust cooled enough to not set it on fire cook its proteins (it wouldn’t have caught fire becsuse the atmosphere didn’t have oxygen yet). Does that sound “rare” to you?

        Life on Earth started damn near immediately (in geologic terms) as soon as the crust cooled enough to not set it on fire cook its proteins (it wouldn’t have caught fire because the atmosphere didn’t have oxygen yet). Does that sound “rare” to you?

        Sounds well done to me.
