I'm so glad to see the growth of "Idealism" as you've mentioned. I think people not only are waking up to it, but it's almost undeniable, since it's considered empirical evidence. Even though empirical evidence is not supported by science, us humans experience it first hand. Therefore, we don't chase trying to prove something that is being experienced simultaneously by thousands up to millions of people. Thus, consciousness is becoming a serious topic even for some famous metaphysicist, especially trying to understand a byproduct of what could consciousness be.
When it comes to Anthropic Principle, I personally have the opposite point of view. I think that the universe was created due to consciousness being present beforehand. Some like to refer to it as God, and some as Energy, some even as Universe, but fundamentally science seems to lack logical explanation when it comes to Universe's creation. If something came out of nothing (Big Bang Theory), then automatically, death is not the end for human beings, and in fact there will never be an end even for universe, because if something can come out of nothing, then there will always be something coming out of nothing, and existing or also known as an endless existence. But, based on our knowledge and empirical evidence, there has to be something in order for something else to come to life, and in my opinion, consciousness has existed long before anything else. Is it God? Could be. Is it Energy? Also could be. But, I'm certain consciousness is the fundamental dimension of any existence. This is contradictory with the above written hypothesis, but if I'd delve deeper to explain the details of my thought pattern on this matter, it would make sense.
My hypothesis supports the fact that death in either case is not the end. Regardless of the conclusion on how universe was created, death seems to be just a transitioning phase for humans and other living beings that possess consciousness. In a way I think that -
Consciousness is not a byproduct of the universe, it is the source of it.
As you mentioned, "in an unrealised universe, birth and death may as well happen in the same instant", I couldn’t agree more. It really does feel like they happen all at once.
What I think is fundamentally flawed in today’s philosophy, physics, and religion is their refusal to coexist or even complement one another. They don't need to fully agree all the time, but when a philosophical idea leans toward something spiritual or religious, I don’t see why people are so quick to rebrand it as just “energy” instead of calling it what it might simply be: God. Or the other way around.
From what I’ve been observing, science has almost become a religion of its own, often dismissive, even arrogant, toward anything that doesn’t fit its framework. If something can’t be proven in a lab, it’s instantly labeled as false, no matter how real or widespread the human experience of it may be. Too many scientists seem too eager to ignore or invalidate empirical evidence simply because it doesn’t come wrapped in formulas and peer-reviewed studies.
