I'm glad to discuss it, but that's all the evidence you're ever going to get, if you personally have not experienced... it. Through meditation, psychedelia, or religious practice. First-hand witness accounts and historical records are your evidence. How long you ignore it all is up to you.
Once upon a time I was locked in a mind prison of material logic. I considered myself transhuman, dreamed of cybernetics and the singularity. Thought that all religious peoples are idiots stuck in ancient fairy tales. Then I experienced a sequence of odd coincidences and inexplicable situations where spiritual entities guided me, causing a complete deconstruction of my entire worldview.
Now it's obvious to me the truth I had been so vehemently running away from my whole life, and the propaganda, indoctrination, and brainwashing are laid bare before me to see. The modern "we don't need no God" ideology is literally terminally ill. Everyone who blindly follows science and government are being consumed by them. Fertility is falling off a cliff. They're all mentally ill and medicated. Mandatory medical genetic experiments and engineered bioweapon plagues are murdering its followers and the fact that this ongoing debacle is being actively suppressed in media and politics tells me clear as day, the devil himself has taken root and hold of this world.
Meanwhile, in the churches I frequent, I see happy families practically building paradise on Earth, the kind I got to see as a child, and I know most people are headed to the same hell I climbed out of, like zombies. No amount of talking with these self-destructive delusionists will convince them to even try praying once in their lives, even as a joke.
I have all the evidence I need; My life has made a miraculous turnaround from spiritual guidance. If you'd like, I can ask the spirits to guide you through me.
The main thing to know about the spirit world is this: Good spirits require your explicit permission to come aboard and help you. The bad ones invite themselves in and destroy you from within. That's why humans are fundamentally religious creatures, and you ignore the spirit world at your own peril.
It's like the microbiome in your body. You gotta let good/neutral bacteria make a home of you, lest the bad ones take residence and literally kill you from within. And it's not "you fall dead the moment you stop believing", it's "these hostile bacteria literally control your mind to cause unhealthy behavior for their benefit", like overeating sugar (obesity very prevalent), being selfish, greedy, etc.
A prayer a day keeps the evil spirits away. This is not a matter of faith for me, it's the truth I've experienced for myself, and the evidence for which I see written in our very civilizational DNA. You just choose to ignore the evidence because you think yourself bigger than God. It's an indefensible position the ramifications of which you'll regret when it's too late, or when you hit your personal rock bottom, as I did.
