I’ve always wondered why it’s nearly a constant theme: “Must Have Water” for life
What is so special about water? Sure, it’s essential for most of the “life” we are aware of, but that’s as narrow minded as saying Well if they don’t speak English, it must not be intelligent.
Aren’t there other substances that could provide the same functionality…Substances we aren’t even aware of, that exist under “extreme” (to us) conditions where H2O may not be possible in liquid form?
Speaking of which, did you see where they suspect a lot of H2O on the moon, but it is so distributed that it can’t / doesn’t form pools or ice as we’re familiar with.
