Why is that? This is essentially an argument from ignorance. If the physical forces are themselves the creator then we could still have existence. Nobody knows either way, and so your argument for a creator is an argument from ignorance.
Thats your opinion,either that or you are a fool,to say that physical forces could be the creator is like saying that you could lay down all the parts necessary to build a car,and with no help at all at some point in time that car would be put together,I dont think so.
As far as your point, I dont see that you have made one.
