I'm not really sure what your point is. The ''everything'' had to come from somewhere, the inertia had to come from somewhere, so how are you reaching the conclusion that theism or a religious explanation is somehow illogical here? I mean, you are saying everything always was, but this type of theory has no ''proof'', in anything that we observe. WE DO NOT ACTUALLY OBSERVE INERTIA COMING FROM ''NOWHERE''. It is always coming from ''somewhere'', just at far distances, so a point of source is not known.
Sure it did. Or maybe it always was. There's certainly no evidence that there has ever been nothing.
That's the point. Everything is everything. We have never recorded and instance of nothing, because we exist in the everything. As such, science has never stated that everything came from nothing.
Everything came from everything.
The gaps in knowledge certainly provide reason for faith in the supernatural, and I'm not saying that they are illogical. They're simply unsupported.
If you say "Well that gap in knowledge is where god did some stuff" then fine. The next obvious question is "what did god do, specifically, and how did he do it?" Likewise, what do you do with your argument for god when said gap in knowledge is filled? Do you just move on to another gap in knowledge and hope that faith can reside there?
Faith and theology and religion can throw some guesses on the table, but there's nothing to substantiate them other than desire, wishful thinking, bias, preference...whatever you want to call it. They aren't bad, necessarily. They're just baseless.
On the accusation that there is no proof that everything always was, can you cite an example of there every being nothing? If you cannot, then you cannot make the claim that nothing precluded everything. And there is plenty of evidence that everything always was. Matter changes form and function, and can vary in quantity and location, but it does not diminish.

Now, as a caveat, there are some ongoing studies and some data which implies that our closed system of a Universe may not be closed at all, which would have much broader implications than just arguing about the Big Bang. This new data could also validate the Multiverse theory, or not. We just don't know yet. And that's cool.
I think it's a much more defensible stance to cite ignorance of a topic than to feign knowledge where there is none.
