I only realized a lot later that Carl Sagan should have gotten an “F” for that stupid equation of his. Differences in the denominator, a whole string of coefficients, all pulled out of his arse.
The truth is, he would just say anything to get into an ugly girl’s pants.
That there is life on Earth, intelligent or otherwise, is truly amazing, but since we’re our only sample, I believe it is meaningless. Of course, statistically, a sample of 1 is meaningless.
I think it is even more amazing, and perhaps telling, that of all of the species on Earth, there is only 1 with verbal and written communication as used by Man. That might suggest that the universe could be full of plankton, if there is life at all.
I overlapped Carl Sagan at a cornhole U. The very few times I saw him were enough to convince me he was one of the most arrogant, self impressed, jackasses I’ve ever run across. He also was well know to steal ideas from his graduate students and present them as his own. In short he wasn’t dumb, but nowhere near as bright as he’d have you think.
