I agree. However the vise-versa wasn't the subject.
I don't believe in gods but one thing we can't deny is everything we know of that exists or existed, came from something else. Where do we draw the line and say this is "it", this is where everything came from and nothing came before it and can we show it correct with evidence?
Well, there are several possible options:
1. Infinite regress: there is a string of causes going infinitely back in time. many people seem to dislike this option, but there is no logical reason it can't be the case. There are variants of this where there is an infinite regress in a finite amount of time.
2. There are uncaused causes: because of quantum effects, this seems to be the case. In fact, there are probably many uncaused causes (even within the universe). Many deists want to limit there to be only one uncaused cause, without proof.
3. The concept of causality loses its meaning: when applied to the whole of spacetime, this seems to be the case: causality only makes sense *within* spacetime.
The problem is that we simply don't know, at this point, whether it is even meaningful to talk about 'before the Big Bang'. it may well be that time simply cannot be extended past that point and the word 'before' is nonsense at that point (sort of like 'north' at the North pole).
Even if it is possible for time to make sense prior to the Big Bang, it is far from clear what sort of causal properties (laws of physics) would apply. And, even if there are such laws, it is far from clear there isn't simply an infinite regress.
Why adding a creator solves any of these problems is beyond me.
