I go back and forth. Part of me thinks we are just lucky and by chance life formed on this planet in a specific way in a specific time. That luck and chance was so long at odds that maybe we are alone.
I've actually been thinking about that recently. I think there may be a few books to seek out, but I'm trying to comprehend the magnitude of the mathematics.
Talking just life evolving from single/simple cells to man. Evolution occurs rather slowly, and just think about all the genetic mutations that have to occur to get from single cells to man. Even over a period of 500M years, it's hard to believe there wasn't some sort of intervention. And then how do you explain the gaps - the lack of a true missing link and the huge disparity in intelligence between man and virtually every other animal on the plant. You have a singular evolutionary branch for man, and it continues linearly with no other real branches off? I'm not sure survival of the fittest really explains the comparative lack of variation in man relative to other animals.
But go back a step further. If the dinosaurs don't go extinct, would man have ever been able to advance like we did? Go back even further - you can't have life without water.....and you can't have water without an atmosphere.....but you can't have an atmosphere without water. The argument goes with a 100 Billion Trillion chances, eventually you get an Earth. But our search for similar planets may not yield anywhere near those number of chances, which are believed to be nearly inifinte.
So basically I think you end-up with if we are the result of randomness, then several other forms of intelligent life must exist in the universe no matter how astronomical the odds of that randomness. And if there was some sort of intelligent design, then by definition we are not alone. And in such a large universe, why would said designers stop with only one planet?
Put me down for "not alone", but the universe is probably not "teaming with life".
