As an option, the model of the universe may be such: it has a beginning, and before it — the era of the initial homogeneous physical reality, often called the era of Nothing. It originated spontaneously with the self-organizing matter appearing spontaneously and evolved further. In form and structure — a multilevel Multiverse, and its properties allow it to develop further and exist eternally, but may not without the participation of intelligent beings. Yes, today this assumption, as a general view of the world's limits, does not have a full proper explanation, but it, as a philosophical hypothesis, makes sense, which can be termed beternism — "beternism", from the words beginning — "beginning", and eternity — "eternity".
