"We have certain tools to slowly investigate the physical laws of the universe, and we sorta think right now that somewhere about 14-15 Billion years ago, 'something' happened that 'caused' all the complexity we see now. "

So now it's thought that 2 umtpy-umpteen-dimensioned 'membranes' collided, starting off our 'Big Bang... but that way of course leads to madness - 'just what were all (and how many of them?) those 'branes' doing floating around (in what?), and what 'created' them.'...

"They're coming to take me away, Ha ha!"

Sorta ends up like going down that path that leads to serious discussions on just how many Angels can dance on the head of a pin...
