I already did. It wasn't from the Bible, therefore it was from the devil.
Yes, but there are ultimately only two choices. Either something exists eternally, whether you want to be a materialist, a pantheist, a theist, or whatever else about it, or at some point physical reality sprang out of nothing for no reason whatsoever. Quantum vacuums, prior universes, and so forth and so on puts you firmly in the first category. It is not uncommon these days to view the second option as a possibility as well, which strikes me as the heights of insanity, but to each their own.
Yeah. I don't rule this out as a possibility, but it's not the only one even from a more theistic perspective.
Yeah, I operate vaguely within the same tradition. Though there's a bit of Heidegger in there too. And some Aquinas. And half a dozen other things, Western and Eastern alike.
