Where did the material come from prior to a big bang that formed everything known to man!

Wow that's deep stuff. Can that reasoning be applied to things people have a belief that is etched in stone about, or just things with no absolute answer? I'm curious about that because it seems that what is good for the goose isn't good for the gander when it comes to certain topics. Just my gut feeling on this one.
To back my simple thought up here is an exchange between myself and my Mother that took place just three days ago.
Mom: I hear that you question whether or not there really is a God, is this true?
Cole: Yes it's true.
Mom: Why? Just look around at everything, where did all of this stuff come from?
Cole: Millions and millions of years worth of evolution, long periods of change.
Mom: Don't you believe in Heaven?
Cole: Not sure it exists, and if it does then it's my loss and no one else, my choice.
Cole: It's all based on a belief system rooted in some sort of faith anyway, so who's to say. Nobody KNOWS for sure one way or the other.
Mom: Yes but what if it's true and you find out only after you die?
Cole: That's the whole point isn't it, the hook, the idea behind several hundred religions all sparring over one supreme being.
Cole: What if after you die nothing happens, no heaven, no peaceful garden?
Mom: " THEN I'VE LOST NOTHING " and if it is true " THEN YOU HAVE LOST EVERYTHING "
It ended there as I drifted into a funk and suggested that a change of topic was in immediate order.
The research done for and against fill many a book at Universities and public libraries all over the world yet the question still goes UNANSWERED. I really don't think that there is much more to say about it. It's pretty easy to see that there are some things that are not supposed to have answers.
