One final attempt to try and get through to you guys

[Ben Davis]

I don't know what was before then. And neither do you.

But how did nothing become something? I'm genuinely curious.

No-one with any knowledge of the subject suggests this, it's just a misrepresentation used by religious fundamentalists in order to mislead those who have little knowledge regarding the beginnings of our universe. The consensus of educated opinion, based on the evidence that we currently have, leads us to the conclusion that before the space/time/matter expansion (the Big Bang) of the current form of our universe, there was a singularity. A singularity isn't 'nothing', arguably it's 'everything'. Recent developments in quantum physics are telling us that the 'singularity' may not even have been anything like what we currently understand of singularities (and may arguably need to be called something other than 'singularity'!).

Everything else is strictly in the 'we don't know' category however since none of the evidence suggests anything other than natural mechanisms, there's no reason to postulate any god.
