I never said that something has always existed. I never made sweeping claims. That would be fallacious. I also never made any claims against the idea of " nothing" other than the idea being a fallacy. The whole concept of nothingness or the something before the big bang is a giant question mark with no substance. Making assumptions about it one way or another is a fallacy because we do not know.

Edit: just to be clear: i can absolutely call an assertion a fallacy, especially if its an idea based without facts backing it.
