Not discounting something plausible that I can't prove against makes sense to me.
Sure... but you've taken a step further. Not only have you agreed that the god hypothesis is possible, you think it's more than likely. Not only that, you've accepted that this god is the one of Islam. Now, how you get from A to B to C is where you miss me.
As an atheist, I think it's more likely than not that science is correct, and religion are these made up fairy tales by people who didn't know anything about the universe. Note that I haven't ruled out the possibility of a deistic god -- a creator that put the big bang in motion, and let everything happen. But I won't accept that as true until there is good demonstrable evidence that that is what happened.
