Undoubtedly, a rational and adequate worldview is important, but what is needed for its formation? Open-mindedness, curiosity, questioning, impartiality, and the simple desire to live fully.
The eternal and infinite Universe is eternal physical reincarnation: the eternal existence of everyone in infinitely identical worlds of the Multiverse.
The demands of the times are such that Homo sapiens must swiftly evolve into Homo Sublimis, the Sublime Human. Otherwise, either nature will destroy us or we will destroy ourselves.
If the eternal and infinite Universe is real, more precisely, if an eternal infinite physical space filled with self-organizing, mind-creating matter is possible, then there is a high probability of the emergence of infinite copies of the same intelligent worlds. Yes, from a physical perspective, every intelligent being — merely a specific configuration of particles, and there could be any number of such copies. But in such an eternal Multiverse, super-powerful super-intelligent civilizations would undoubtedly form, which could well be the creators of Universes like ours. While such a possibility is unsettling to us, we may have to come to terms with this possible reality and continue to explore the wonders of infinity.
If the Universe is eternal and absolutely infinite, then its ability to form intelligent beings has always existed and always will be inherent to it. The question then arises: how logical is it to assert that 'if the Universe has no beginning, then beginningless intelligent beings also exist'?
