Take a Memo:
I wanted to add some commentary here from a sort of 'devil's advocate' standpoint. You know, we've all heard the Carl Sagan "billions and billions" arguments for the possibility of life elsewhere in the universe. Now logically it would seem on the surface, the possibility of life is certainly there, and I can't really argue that it isn't a possibility, but the question is probability. Many people see billions and billions of stars and planets, so they assume the probability is fairly high that some other place in the universe could spawn life as we know it.
But... not so fast.
There are literally millions of variables which have to be a certain way or life on Earth does not exist. It's not simply a matter of being 93 million miles from the Sun. There are the essential elements for life as we know it, those have to be present. Then there is the aspect of our moon and how it enables tides in the ocean, instrumental to almost every form of sea life. There is the wobble of the Earth in its rotation which gives us seasons, and what role do seasons play in life? As we can see, the potential candidates are dwindling fast.
When we come to intelligent life... homo sapiens... we wouldn't exist if the dinosaurs hadn't become extinct. That event has to happen to enable mammals to flourish and rise to humans. Now we get into "luck of the dice" things that other planets who have overcome all other obstacles, have to somehow get by. Even with the vast number of planets and stars in the universe, the number of planets with life as we know it, or intelligent life of any kind, is still a small probability.
