In the interest of brevity I won't replay that whole discussion here. Instead let's address your other two arguments. A good start would be to realize that there's a difference between biology and physics. The theory of evolution has nothing to do with the Big Bang theory. Yes, creationists oppose both, but that's about the only connection.
Evolution deals with what happened to life on Earth once it began.
The Big Bang deals with how the entire universe came into being. If the Big Bang theory was somehow proven wrong tomorrow, it would have absolutely no effect on the theory of evolution, and vice versa. The main problem is your initial assumption. According to the Big Bang theory, the universe exploded into being from a singularity. The Big Bang exploded everything outwards, including space itself.
