Though by your argument you admit there's a chain that goes on. What if we are to stop at Cells? We could go further, but if go further, like you said, we could find more. By your own argument, we can find one of two things, either A) God doesn't exist as the chain would stop before him. Something created the very thing you call god. God could simply be that little voice in your head.
Like your god.
Why are you sorry I feel that way? You haven't made an argument. YOU should feel sorry for disappointing all of the theists on this site.
What made god?
But you're own argument limits God's existance. Under your own argument god cannot exist.
