Mindchild,
I've thought many of the same things you mention. Modern physics definitely does point to the existence of a Multiverse. But, when you think about it, doesn't that also just dodge the question? Can we comfortably say, "Well, the reason our universe exists is because it is part of a much larger Multiverse which contains many universes. Surely some of them are bound to have the physical constants necessary for life to evolve. What is more, there are an infinite number of these universes. Whalla! There's the answer!"
But, where did the Multiverse come from? You see, we can go on ad infinitum with this type of reasoning.
A tough question: Does the idea of a Multiverse contradict Occam's Razor as much as does the theory of a God?
Little Toe,
The problem with your thought is that modern phsyicists have recently made calculations which show the universe most likely will not recede in on itself in a "big crunch." It appears it will simply keep expanding......for...ev.....e...............r...........................................................................
