Where did the particles that caused the big bang come from?, if there is answer for that then where did the...

And why is only god allowed to be eternal?
Why is god allowed to not have to be created by something else?

For the record, the christian god is not a logical possibility, as the all-knowing capacity clashes with the absolute determinism that produces evil which is then blamed on the people who are punished for it by an allegedly all loving god. If you cannot follow this, that means most explanation are above your head and explaining further here would be a waste of my time.

If you think that you made a very good point, that means you a biased, and lack enough knowledge to be educated at this point. Read the June 2011 issue of Discover abut black hole creating complete universes, and you may have the beginning of an answer. The rest may take more time.
But jumping to conclusion and claiming that 'goddidit' is a cop-out and a wimp way out. Science does not work with pre-existing conclusions.

there were no particles, particles can come into and out of existence and they do often. and even if we accept that the particles had to come from from some where, apply the same logic to God, where did he come from? also you are linking two completely different theories, the big bang theory, and Darwin's theory of evolution, the only thing that they have in common is that they go against most religious beliefs. with evolution there is an answer, random luck to start, then the best surviving then passing on its improvements. furthermore why does it have to be the Christian God, you say he is the right God, but more people disagree with you than agree with you.
finally, you did not make a god point

This has been an eternal conundrum .....one of the problems is with the question of time and just what time is. A"beginning" and an "end" can really have no meaning if time itself as we know it closes on itself....something like the Moebius Strip....in other words, that nothing ever began nor will ever end but simply IS....period and that time is the creature of mankind or that it is an illusion. According to Quantum Mechanics, particles can come into existence and just as suddenly drop off the edge about like many small islands in the Pacific. We then have to ask, what is matter and how is it distinguishable from so called "empty space" or is there any real distinction....truly great minds were pondering questions such as this at least as far back as Galileo and even the Ancient Greek philosophers themselves seriously advanced the idea of dimensions beyond the physically tangible three.
