I would in fact argue that we know nothing. This is because we have only started these great and rapid discoveries in the past 'few' years. So fast forward in time and i would say we will know a great deal more then we do now. We can make devices with such power yet we cannot solve the simplest...
Ahh, but... Our species is a young one we may think we know it all but in my view.. If there is a God, our minds would not be able to comprehend it and is again foolish of us to think that we possibly could. We know so much of this world yet so little, i'm sure you will agree with me.
The awnser is there is NO evidence for God creating the universe, and frankly why does somebody have to of created it, the reason why this belife came around was that we were looking for explanations that we simply did not have knowlegde to explain. Now i'm not saying that we now know for sure...
