Kimba, "I'm a believer of a more complex theory of our universe........................what if time did not start at the big bang but still continues into the past endlessly............people prefer a starting point. I say no."
Without getting into what time is about, and just excepting for the purpose of debate how we normally see it, I'm not sure the big bang theory rules out a "past" prior to the big bang.
I think the Buddha's theory that nothing comes from nothing, and something must come from something, still can apply when you're talking about the big bang.
