But in theory, ID and Evolution could easily coexist.
No, they cannot!
One is knowledge the other is propaganda from a particular christian sect.
Secondly, one could believe that a world was created by an intelligent being, and that creatures evolved since then.
Creationism and evolution can coexist.
Yes. Some people beleive god created the big bang. A world that just "appeared" doesn't seem right to me. I beleive in got but no religion.
The concept of the Prime Mover is very different from creationism, creationism is Christian propaganda or some type of American Christians propaganda, the Prime Mover is a philosophical hypothesis for the beginning of the universe, it has nothing to do with gods or creationism.
