i dont think that human brain will be able comprehend what happened before the big bang.

 

Uh huh. Because you think so? And have absolutely zero evidence to make anyone else think so?

We can't handle anything before The Big Bang™ with scientific analysis methods, because we don't know if the basics which science is based upon were existent at that time/place. So, it's more of a philosophical question, hence making bjaminwood's argument about the bible more valid than you might want it.

We can create models and run them in reverse though... We can make a guess... There are several people doing this kind of thing... And getting some interesting results...

 

Although there may well be things about the universe that we can't even comprehend....
