The difference between religion and science is that science follows the evidence and also changes according to it, whereas religion is stubborn and unchanging no matter how ridiculous it is, and no matter how much evidence contradicts it. Religion therefore cannot be Truth.
Even though no one will probably read this, I think your logic becomes flawed when you jump from "something caused the universe" to "God caused the universe". It's flawed in that there's no evidence and no reason to jump to the conclusion that there's a god. For all you know it could've been caused naturally or by multiple gods that look like pink pandas. And like others have said, did this god just create the universe and take a nap for the rest of time?
