ayyy lamaos probably do exist. The universe is billions of years old, and in our own galaxy, there are expected to be around 40,000,000,000 planets. And that would be earthlike planets. Specifically orbiting a star in similar proximity as earth does to our sun.
If even a miniscule fraction of those, let's say .0001% have life, that still makes for 4,000,000 life bearing planets. over the course of countless millenia is it not possible that a hand full of those millions of planets gave way to intelligent life?
As for ghosts and psychic phenomena, I see no reason to believe in them, but I don't entirely discount them. We don't know everything about our own planet, or even our own species, and there is an entire universe of dark matter that we are incapable of interacting with or seeing without the use of scientific instruments, that composes the vast, VAST majority of the universe. Perhaps humans' meta thought, the ability to comprehend death, speculate about an afterlife, think about thinking, and so on, potentially creates an impression somewhere that occasionally breaks through and interacts with us. I'm not saying I think any of this exists, but it's not too far from being plausible, imo.
When it comes to so called celestial beings, like deities and such, I can only think of a three reasons for their existence. 1), it's a Boltzmann brain that somehow influences the universe. A Boltzmann brain being "a self aware entity which arises due to random fluctuations out of a state of chaos [as opposed to evolution]". 2) A super advanced society goes End of Evangelion, and merges consciousness in an extradimensional "computer" where each mind is simultaneously it's own and part of a countless collective, our reality exists within the collectives thoughts.. 3) A similarly advanced society, perhaps somewhat less so, creates a super computer that basically does the same thing.
All of this is pseudoscience, and not to be taken seriously.
