Your hypothesis is that the universe from nothing simply came into existence with nothing causing it and nothing pre-existing it?
No. I was just refuting your claim that our universe couldn't have come to be by itself and something from outside had to create it. I know, it doesn't seem to make sense at all, but still it might be the most reasonable assumption like I explained in earlier posts. One more thing though: if we assume we could somehow look at our universe from "outside", it would actually seem to always be there as a four or higher dimensional object of sorts, the space-time. It still is possible you are right about the prime mover but my point is it's just a wild guess, and in no way better than any of the other ideas that don't include a god, and actually raises more problems than solves.
You assume the stance that nothing happens without a reason and everything that exists had to come from somewhere. If this was true, then sure, big bang had to be caused by something. There seem to be three plausible causes: 1) God / Prime Mover / whatever you wanna call it, 2) cyclic universes or 3) some event in some other universe. The problem is, none of these make one bit more sense than the singularity just being there and every one of these models has some serious problems, while the singularity from nowhere -idea is perfectly consistent with all of our (non-religious) knowledge.
Problems with the prime mover include: what or who is he / she / it? Where did he come from or who created him? Where did he find a suitable spot of ENDLESS NOTHINGNESS to place our universe in? How could he have existed without the universe existing? If he did, he is not in any way bound by physics and natural phenomena in our universe, and moves freely in time. So does he have his own time, separate from ours, or does he live in some kind of place where nothing ever happens or changes? If he is affected by time, it logically follows he had to be created by something too. If he isn't, it follows that whenever in his timelessness he "looks" at where our universe is, he actually sees something in there, our universe at a time zero or over! So he actually didn't even have to create it!
Cyclic universe runs into problems with laws of thermodynamics (the entropy one). In addition, there aren't many other ideas for a cyclic universe than a big-bang-big-cruch-cycle, and it seems that big crunch is not going to happen in our universe. It seems it's rather going to be a "Big Rip". How could this lead to a singularity emerging again? I haven't heard of any idea about that, though I don't know enough to say it's not possible. I love the idea of a cyclic universe but I'm afraid that's not the way it is.
The third possibility seems the most plausible to me, that new universes have always been popping up triggered by some event in some other universe. This could be for example a computer simulation where we will some day create a computer simulated universe, inside a computer simulation inside a... I suppose it's just about as likely and weird as our universe being the only one popping out from somewhere, because a chain of events extending infinetely both ways makes about as much sense as one just starting from somewhere.

To me that seems less logical than either the eternal matter in a universe cycle or the Prime Mover hypothetheses. My mind suggests that everything has a cause and the only way I can find out of that is a Prime Mover.
Intuitive, not logical. You do realize your mind might be biased on this, as is everyone's? Of course it seems intuitively obvious to us that everything has a cause, but it has no relevance at all.
