I'm not sure why you were flagged as a troll, because most of those are actually pretty good questions. Ultimately, however, most of those questions cannot reasonably be answered at this time because no experiments have been designed to address them, either because nobody knows how to design experiments that could practially address such questions, or else simply because of our own incomplete understanding of the universe.
It is, however, a far cry to suggest that simply because we do not yet (or will ever) know everything there is to know about the universe is somehow sufficient to probabilistically suggest that the things that we *do* believe that we know about it at any one time are actually entirely wrong... which I suppose someone may have interpreted your post as, and why it may have been flagged as a troll. To be fair, there are plenty of things that we don't even know about the universe that we actually *CAN* observe, while trying to conjecture about aspects of the universe that we have absolutely no technological means to objectively observe (nor based on our current understanding, are we ever likely to) can only be the subject of conjecture, and not science.
Long story short, you aren't liable to find any scientifically sustainable answers to those questions here, and because of how short a period of time that humans ordinarily live compared to the age of the cosmos, you are probably also not likely to find such answers to them in your lifetime. So while you can ask those questions, you shouldn't be surprised when you don't receive helpful answers.
