It’s just a personal belief of mine that species specialization could allow for organisms to survive in conditions that we would not currently think would be survivable.
I don’t necessarily believe that conditions have to be as they are here in order for life to survive. Perhaps in order for earth life to survive, conditions would have to be the same, but for some other type of life form, who knows?
Very true! But, as I said, going by what we know, how life works on Earth, the conditions have to be VERY special.
Can there be silicon based life? Maybe, but, as far as I know not being a chemist, silicon doesn’t form large chain molecules like carbon does. And the Universe seems to have a lot (comparatively speaking) of carbon molecules floating around. There are even nebulae that are nothing but alcohol, and, not the wood grain stuff.
So, I won’t be shocked if there is something out there, but, won’t be disappointed either.
Again, I think if we ARE being visited, going by the reports we get about it, they are a bunch of morons.
