Before the Big Bang?

As an Atheist, this is something that I am always asked when I debate theists.  I never have an answer for it, I'm not even sure one exists.

What happened BEFORE the big bang, what caused it?  Are there any speculations?

I don't think there are any theories with any real weight, we just don't really have any information about how to describe a pre-big-bang state. It's possibly impossible to find out. That doesn't mean we can't create consistent theories, but it makes them impossible to verify.

Of course, from the theist debate perspective, slotting God in there doesn't solve any of these problems and gains you nothing from an explanation perspective. It's just another consistent but unprovable theory. It is strangely difficult to convince people that 'we don't know' is a better answer than 'we didn't know until we made up an explanation and assumed it was true'.
