All questions about the existence can be summarized and formed into a following one:
Did this universe exist always permanently or was it created at some certain moment?
Accordingly the answers are:
1. It existed always.
2. It was born at a certain time.
I’ll try to prove that both assertions are true simultaneously that seems illogical at first sight.
If we try to prove the first assertion, then the origin of the universe will remain unclear, because it means that the universe hadn’t ever originated from something and it exists eternally long. We can not either prove or deny it, so I’ll begin to analyze the possibility of the second assertion being true, i.e. if there’s any possibility of it being true.
I’ll put it forward as a conception:
If we assume that the world was created at a certain moment we assume that it was created from “nothing”, (i.e. we automatically assume that only “nothing” existed before creation of the world). One can ask how this universe could have been created from “nothing”, or rather how anything could have been created from it. That’s impossible because “nothing” is unchangeable. I partly agree that it isn’t changeable, but that doesn’t mean that any process can’t take place within it. The process of splitting of it into two equal opposite parts can. At the same time “nothing” remains itself without change, or rather the process of splitting of it doesn’t reflect on it-“nothing” itself doesn’t change, but this process of splitting happens within it:
if some “expansion” happens and the term-expansion implies process of rarefaction from one “point” to “all sides”, which is called by us a three dimensional space, “nothing” replies to mentioned process in the same “point” by opposite process of consolidation, which is directed from all sides to mentioned point and is called by us a gravitation, i.e. called by us a body), even we can say that “nothing” is very flexible and it’s able to reply to all processes (happening within it) by their opposite processes, even this can last during the time (e.g. if summer lasts for Three months winter lasts that long too).

We can find that any appearance consists of two opposite processes, but it doesn’t matter in our particular case. Presently I’m not going to prove that that’s really so.
The most important is that “nothing” doesn’t exist within time and space (i.e. the existence of it without splitting doesn’t last during the time) and if this universe was actually created from it, then it was created just after of a die of previously existed universe and there wasn’t any break (which lasted within time) between these two existences, which I’d like to prove, i.e. this universe (might with some interruptions) exists permanently in the space during the time (since the mentioned interruptions didn’t take place during the time).
