@Smileyrius,
Hawking is the expert I am not however by the very nature of a singularity nothing can be
said one way or another about before time and space came into being from that singularity.
A singularity is a break point and a barrier for the flow of information as must as it is a beginning.
There might had been time and space before the singularity there is under current theory no way of knowing.
There are however all kinds of theories concerning super universes etc and new theories that information might even be able to get "pass" even a singularity in short get Hawking books and read them.
To sum up we do not know any more then the Greek knew about lighting bolts.
Lack of knowledge is to me however is not reason to wave our hands into the air and declare a god is behind the curtain of the singularity.
