Wow! I am glad to see that this thread has (hopefully) sparked a good, deep, debate! That's what I was hoping for. That's why I kept my initial post short and concise -- kind of an overview or outline of the arguments for God's existence, and not a long, deep post including every detail of each argument. I will go into the details and logic of each argument in my replies to all of you.
Below I am going to start to reply to everyone in the order that they posted:

"Interesting arguments, but each is flawed so not really a proof for God."
Well, I agree that 100% proof does not exist for God (or nearly anything for that matter), and it also depends on what criteria you accept as "evidence" or "proof."
Now, whether or not they are "flawed" is something we can debate here.

"[Quoting UnDisfellowshipped: Big Bang - Everything that begins to exist has a cause]. This is not strictly correct, everything did not begin at the big bang, the theory is that there was already a point mass that exploded at the big bang. If you remove the word "begins" it is still falls apart in this theory that states that God exists but without a cause."
Correct me if I am wrong on this, but it is my understanding that the Big Bang Theory says that Time, Space, and Matter all began in an instant, either at the Big Bang Explosion, or right before the Big Bang Explosion. Does science say anything about how or what kind of "point mass" would have existed before Time or Matter or Space existed?
Scientifically speaking, before the instant when Time, Space, and Matter began to exist, wouldn't nothing have existed (at least nothing physical)? If nothing physical existed before the instant when Time, Space, and Matter began, then how is it even possible for Time, Space, and Matter to come into existence, without a cause?
Now, about God not having a beginning: The way I understand it, either Something has always existed, or Some one has always existed . So, it just all boils down to which one makes the most sense logically, and fits into the available evidence best.
Basically, the way I see it, you have three choices as to what to believe about the Origin of the Universe:
1:) The Universe (Time, Space, and Matter) always existed. (But this is shown to be wrong from all of the modern evidence for the Big Bang Theory)
2:) The Universe (Time, Space, and Matter) was caused to exist by some Timeless, Spaceless, Non-Physical Being.
3:) The Universe (Time, Space, and Matter) came into existence on its own, with no cause, from nothing, for no reason.
Option # 2 seems the most reasonable to me out of those three choices.
