What does science have to do with anything?
It illustrates how useful NOT making religious assumptions is. Making religious asumptions ONLY serves those who want religious conclusions, not truth, not knowledge.
There are no "correct" existential answers. That kind of truth is not available to us.
Yet theists often claim there is. And based on what? Old books that don;t contain factual information. So yeah, scared of death? Get therapy because religion will only put a bandaid on it that will never help face reality.
What people believe has never been relevant to anyone but the believer.
Tell that to the religious right in the USA about reproductive rights, and the freedom of gays and trans kids who use religion to limit freedom and public safety.
Then or now. Nor does it effect the self-evident awareness of the great mystery of existence that most people refer to as "God" (in English, anyway).
Yeah, the self-created mystery of existence that is not really valid from a rational perspective. Why, you ask? Because religions feed all sorts of non-factual ideas that believers assume are true, and then this bad framework they struggle to make sense of their life experience. Look at all the Abrahamics who don't care about this life and look forward to heaven, as if that is a sane and rational approach. They were fed these ideas and through their gulibility their lives are consumed with illusions, and not living.
Your whole world view seems to be confined to whatever can fit into a science textbook.
False, I race bikes, I'm in a band, I have a business that keeps me way too busy, and I have no need to rely on religious concepts for meaning. I do rely on science to inform me about what is true about our universe. Why, you ask? Because it follows facts and has a reliable method to distill truth, unlike religions. If religions followed facts and used a rational basis for their conclusions then I would respect that method too. But it doesn't. Religions work to perpetuate old traditions of belief, and that's all.
While existence is so much greater than that. Not even all our science, all our religion, all our philosophy and all our art combined can even reveal it's edges to us. Let alone it's essence.
I think people get too wrapped up in defining what life is that they don't live it.
