Of course. I can't make you stop believing something. But being stubborn is also nothing to be proud of. When new information overturns a belief, our views should change.
As for your question: https://en.wikipedia.org/wiki/Zero-energy_universe
You cannot get 1 from 0. This is the reason for your belief in a supernatural creator. However, you can get 1 and -1 from zero. If you add 1 and -1 together, the result is 0 (nothingness). Logically this also means the reverse operation is possible: Dividing 0 in two gives you 1 and -1.
The 1 in this case is all conventional matter and energy. The -1 is negative gravitational energy. The experimental confirmation of this hypothesis was the observation that the quantity of observed negative gravitational energy in the part of the universe we're able to see from Earth appears to match exactly the amount (and distribution) of matter and energy. That's an awfully big coincidence if this idea isn't true.
So, what caused that division? You can say "It was a big magic man in space named Yahweh!" But then, where did he come from? If nothing can exist uncaused, then Yahweh needs to be caused. If you assert without evidence that Yahweh can exist uncaused, I can assert without evidence that the universe can exist uncaused, with equal validity. That's not to say it's true, but that at this stage, our explanations would be on even footing.
This is why postulating an intelligent supernatural creator doesn't actually solve the problem of explaining where everything came from. There's also logically no way to go from "there is a creator because the universe cannot self-originate" to "the creator is specifically Yahweh, god of Judaism, Christianity and Islam". It could just as easily be the creator god of any other religion.
I do think there is good reason to believe the cause of the big bang was natural though, for the simple reason that every time in history we have discovered the cause of a natural phenomenon (like weather, volcanoes, rock formations, snowflakes, etc.) it always turned out to be a natural process. So far, nothing has been shown by experiment to have originated supernaturally. Why would the universe be any different?
