Why does one assume that it cannot?
Simply the fact that it is so complex. I'm not saying it's impossible, it just seems ridiculously unlikely. In my philosophy of science they had the actual probibility rate that even the simplist life could evolve in an atmosphere with all the right conditions, and it was astronomically slim.
The idea that theres something out there that we just can't understand that affects those probabilities just seems like a no brainer to me compared the the opposite.
Have you ever read Finnegans Wake, by James Joyce. I tried once and came to the conclusion that I was just not smart enough to understand that book. Thats how I feel about God. The substance is there. I may be smart enough to see that the substance is there. I'm just not smart enough to get it.
Back in the day before they figured out eliptical orbits, they figured that all orbits were circular. They didn't have concept of gravity, so from a geometric standpoint circles just made the most rational sense. But their empricaly data, the path they saw planets and stars take, didn't match circles. So they would figure that the planet was orbiting around something that was on that orbital parth. Or orbiting around something that was orbiting around something that was orbiting around something that was orbiting around earth. I get the feeling from sciences in general, especially evolution and quantum or astral physics. That this is what they're doing now. Evolution, as a basic theory is valid, but they got some little thing wrong, they misplaced a decimal, and now they're trying to put circles on circles on circles, and yes it works on paper, but its so complicated and requires so much improbable shit to happen that it just doesn't make logical sense. And one day they're going to figure something else out, and go, oh the orbits aren't circular, they're elliptical, now everything works and is pretty simple!
I'm not saying they should just be like “oh, well, its because of God, lets move on” They should keep testing, and find out what's really happening. My issue is with general population that give credit to science that it's not nessecarily due. By it's nature science is always changing. But people assume that contemporary theories are set in stone. After all the mistakes that science has made in the past, you'd think people would be slower to believe something as fact just because science says so.
