Beside the ignorant comments you made, I have never read where anyone suggested that ''science'' caused anything to exist. Science is a process of discovery. Science has no powers to magically / supernaturally cause something to exist as you claim your gods have.What's he's saying is that it's unbelievable that everything came about by accident or due to science, therefore a 'god' of some description must have been responsible. In his case it is probably the Christian god, as opposed to the plethora of other gods. However, when you point out the fact that if you take that to its logical conclusion - ie, well, where did the god come from? - that's where the hypocrisy comes in. "Oh, he always was". To which I say, "oh, right. So when it suits you, something can come from nothing, but when it fucks up your narrative, then there had to be some supernatural being involved." No wonder religion is slowly going the way of the Dodo.
What Dr Grump is apparently saying is that something has not necessarily always existed; hence, the cosmos just popped into existence from an ontological nothingness or that science(?!) caused everything to exist.

By the way, what, precisely, is this science thingy that caused everything else to exist before, mind you, this science thingy existed?
You want to rewrite that mindless gibberish, sport, or are you just going to let it hang out there for God and everybody else to see just how foolish you are?
While you're thumping your Bible, I would advise that a book is simply that, a book. Until there is a way to connect a supernatural being with the authorship of a book, it's safe to assume that the book is, in fact, merely written by men. Similarly, your claims to a version of polytheistic gods are mere unsubstantiated claims until you can offer something connecting your gods to anything in the natural, rational world.
