Brain Boy

I have a theory, if space really is endless then how did the big bang happen because space is empty and has no matter in it and no atoms which is the fabric of space and time then how is it possible for matter to be created because there is no time, no atoms and most importantly life so anybody know the answer to how the big bang happened cause I got nothing but I don't think space is endless because no mind can handle that there is an endless thing cause it just can't be endless it's just too mind muddling I mean theres got to be something else past space I mean it's like trying to tell the time when there isn't any time at all. | PS: sorry for the long sentence.
