“...probability of even ten of these variable existing all within the extremely narrow range necessary for life as we know it ...”
Few can grasp of the point your making here. I have the idea, but fully fathom the magnitude of improbability. Of course “as we know it” is quite the caveat too.
Granted. But it's the only thing we have to go on. To start speculating on some other type of life form is to leave the realm of science and enter the realm of science fiction. (which does make for a good bar scene in Star Wars though)
