The very fact of our existence is a miracle that causes surprise even the greatest minds. For primordial self-organizing matter is impossible, and hence it spontaneously acquired this self-organizing property which led to the emergence of the Universe followed by the birth of life on planet Earth and the formation of Homo sapiens.
Does time have a beginning? Yes, but also, conditionally, no. Our world most likely had a beginning, but before that, as it's commonly referred to, there was 'Nothing'. Logically considering, this 'Nothing' represents a physical reality that is finite in volume, within which time loses all meaning. This matter, though possessing the potential for evolution, doesn't yet have self-organizing properties. Its motionless state or simple, monotonous oscillations, regardless of duration, equate to absolute non-existence. Consequently, "meaningful" time commences with the emergence of "meaningful" movements of physical reality, or more precisely, when matter spontaneously acquires a self-organizing property. This property acts as the catalyst for the rise of complex phenomena.
The beginning of time, and consequently the universe — the moment when self-organizing matter spontaneously originated: either it acquired this property that it previously did not possess, or it appeared from the absolute Nothing, if such a thing is possible in principle.
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".
If infinite space filled with eternal self-organizing matter is possible, then there arises a situation where there is an intelligent world that doesn't know its beginning, which is contradictory. Therefore, the primordial self-organizing matter is impossible. The such matter must have a beginning, and if there was other matter before it, it must have been without such property and also not infinite in space. At some point, this primitive matter accidentally acquired a property capable of giving birth to ultra-complex, whimsical phenomena over time. This moment can be considered the beginning of time, the origin of the universe and true being, and before it — the Era of Nothing.
Which questions will remain unanswered by scientists? There are no questions that science will not eventually be able to comprehend and explain, it is only a matter of time. There may be certain details that are not crucial for understanding the overall picture of the world. For instance, perhaps, science may never give an exact answer to the question: How much time has passed before self-organizing matter appeared?, but since that period was the Era of Nothing, the concept of time loses its meaning, and therefore the answer to this question is not so important.
Matter possessing self-organizing property must have a beginning. If infinite space filled with eternal self-organizing matter is possible then there arises a situation where there is an intelligent world that doesn't know its beginning, which is contradictory.
