If you don't mind, I'll just tackle the whole, "where did all the energy and matter come from" question.

Obviously it all came about as a result of the big bang. However, this poses a further question which is what was before the big bang? There are two answers to this that I can see. The first is of course that all the energy of the Universe was wrapped up with the singularity that subsequently went 'bang' (technically it didn't actually go bang but I won't quibble about that now).

Now, there is no reason to presume that this singularity didn't always exist. There are two reasons to suppose this, firstly it may well be that there was never a time, now matter how far back you travel, that either the singularity or universe or something else didn't exist, the universe that we currently inhabit simply being the form it happens to take today.

Secondly, if, as some suspect, time itself came into existence along with everything else at the point of the big bang then the whole question of what was before and where did it all come from become meaningless questions.

Personally I favour the string theory argument from which M theory is derived whereby the big bang that brought about our universe was as a result of two colliding membranes floating around in the multiverse. If this is true, and it seems pretty plausible and is certainly supported by the maths then there would have been multiple big bangs not only on the membrane that this universe exists but also on our partner membrane. The multiverse of course may have always existed.

Any of these answers seem far more probable than simply saying "God did it."
