Oh, forgot to reply to one more point...

By the way, the funny thing about Science, is the hidden understanding that when the next best explanation is discovered, it will out of necessity supplant and rip out by the roots the old way.

This is not a hidden understanding. It is the most basic tenet of science itself. Science is constantly searching for better answers. Provided that there's testable evidence and that the questions are empirical ones.

Perhaps nothing in Science can explain what came before the big bang, but not knowing does not cause the current explanation of things to poof away either.

And just for the record, I'm not completely down with the whole Big Bang thing anyway. That's a pretty shaky one if you ask me. Our evidence about of the origins of the universe is sketchy at best. That's one of those areas of science where I expect to see changes in CW as time goes by.
