As an option, a model of the universe could be as follows: it has a beginning, preceded by the Era of Nothing, it emerged with the spontaneous appearance of self-organizing matter and has since evolved. Its structure is a Multiverse or a collection of Multiverses, and its properties enable it to continue to develop and exist eternally. Indeed, at present this assumption, as a comprehensive view on the world's boundaries, lacks a complete and adequate explanation, but as a hypothesis, it warrants recognition, which can be designated by the term "beternism", from the words "beginning" and "eternity".
During the inception of our Universe, fortuitously arose a small possibility that under certain circumstances there might come into existence at least a single primitive intelligent being. The planet upon which this would occur remained a mystery, and the emergence of intelligence on Earth is not miraculous. This could have materialized on another celestial body, and a thinking being similar to us would likewise ponder: why us, why here? It's a matter of chance, you're simply fortunate, your planet won the cosmic lottery.
What should the world be like for its existence to be possible? A world that, like ours, is capable on its own and without cause of giving birth to intelligent beings. In particular, should it be finite or infinite, having a beginning or being beginningless?
The origin of intelligence, is it a mandatory and 'inevitable' property of reality? No, it's causeless and spontaneous. Reality could have existed in a primitive form without the self-organizing property. So why does the Universe possess this property, thanks to which intelligence arose in the process of evolution? Just, without a cause. Without this property, no questioning being would have emerged.
The existence of such a curious creature as humans suggests the existence of a Universe just like ours. And this doesn't mean it was planned this way or that this is the only possible mode of existence. Reality could have had other properties that would not allow for the emergence of any kind of intelligent beings. Yet, fortunately for us, reality is just as it is.
Does the universe have a beginning and a purpose? - a) no beginning and no purpose; b) no beginning, but there is a purpose; c) there is a beginning, but no purpose; d) there is a beginning, and there is a purpose.
The causality of events post the Big Bang is clear. But if we consistently "move" backwards, at the most basic level of physical reality's existence, it should culminate where matter, as the "prime cause of the world", should not possess a reason for its existence and a cause for its initial motion. It simply exists just without a cause and possesses the opportunity to spontaneously evolve.
Reflecting on the finitude and infinity of the world, if we assume that the world is a Multiverse and it is not infinite, then what can be imagined beyond its limits? Absolute emptiness, or is there a logical model where the emptiness disappears?
