There is a difference between an explanation for phenomenon we have no evidence for and pulling some random thing out of a hat and saying it's real.
the pink dragon created the universe! now its an explanation.
You sound like that child on the playground playing guns with another kid, the one that always says he just managed to dodge before getting hit. Right there, you are changing the rules. It's something different from what it was when first proposed.
Also, has anyone been destroyed by it for not sacrificing their first born? No. In this particular case, you are saying it does something that we know for a fact does not happen. You can see this by looking at records of everyone's first born. A lot of them end up growing up, in case you haven't noticed, and the parents might die of, say, cancer or a car crash or from just being old.
You've pulled out of a hat some random explanation for something that does not occur.Now as far as creating the universe goes, we don't know how the hell that happened, not for sure. We have no way of monitoring the event. No records. No way of detecting whether or not there are gods to do it. Maybe there weren't, as I said before, but there's nothing saying that it is a fact.
Edit: Basically, how do you know you are right if the opposing side cannot be disproven? (this question applies to you whether you believe in a religion or not)
