I believe that humans are "special" in the universe.
Could humans have developed on other planets?
I find that very very, VERY unlikely. Humans are something that evolved on this planet. For there to be humans elsewhere in the universe, everything would have to be exactly like our planet.
For example, exactly one AU from a star, a star exactly one solar mass, exactly the same amount gases in the planets atmosphere as ours, a planet with exactly the same gravity as ours, one Moon which has exactly the same mass as ours, the major extinction events, and the list just keeps going on and on,...
The odds are staggering. Although its likely life exists elsewhere, but I find it hard to believe that they will look anything like humans.
I do find it quite amusing that all this might well be taken as an argument for some kind of design in the evolutionary process, or even a designer God ....
it's a fascinating question, isn't it. Is it more likely that conditions being just right are the result of just the right coincidences having happened, and we're just the end result of a very long process of incredibly precise natural selection, or that there may have been some planning, and/or some direction, along the way? I wonder why so many see this as such an outlandish and absurd and preposterous and downright insane notion?
... and then, of course, if the latter insane and absurd suggestion
was in fact the case, then why should we suppose that we are the specially Chosen ones, and this was the only planet on which such a thing may have been done? That would be remarkably arrogant, wouldn't it. Who knows, perhaps life might have been "promoted", if you like, or conditions adjusted so that they were just right, on many different planets ... ?
...but that's such an absurd and insane and downright running-round-in-circles-drooling-at-the-Mouth notion that no sane and rational person would possibly entertain it for a minute, isn't it.
