No problem @senu. Either God exists or he doesn't. I can't prove he does exist but you also can't prove he doesn't exist. So we have to look at evidence to support whether or not he exists. Now we know nothing can be made without a maker. The same goes for what we see in nature. It did not just come from nothing. Something cannot come from nothing. It's impossible. There must be a creator in order to make something.
You may not see the builder of a car but you know someone built it. So the question to you is why do we have something instead of nothing?
