In order to disprove intelligent design, you have to prove creation by some other means. We cannot prove that the universe was created, nor can we prove that the universe started off with the big bang theory, because we were not there to observe it. So we can neither prove nor disprove evolution, the same way we can neither disprove or prove evolution, because our scientific method forbids us from assuming that the Big Bang is common fact, as much as it forbids us from claiming Creation as common fact. I actually don't care what our origins are. And despite what scientists say, evolution is not a key integral in science, physics, or astronomy. We know that things can and tend to drift because they have the space to drift, we cannot prove that galaxies are getting farther away from each other because of the big bang and a rapidly expanding universe. Galaxies would be claimed by gravity, larger galaxies being absorbed into smaller galaxies for instance, same sized galaxies orbiting each other, etc. Does anyone know the exact size of the so-called beginning particle? If so, how did it come around (it would give the big bang theory credibility, but it would open more doors to which our current science does not have the means of going through).
