The conclusion that I've arrived at from research and experience is that God is real. What/who He is exactly still slips my grasp. I still have a ton of questions. So does science. Why are we the only planet with life for millions of light years? How did we evolve in such a short period of time? Are there other dimensions? Can we access them? The list goes on. In the end, I conclude that it's either luck, God, or aliens. To me, I feel like it's a mix of the last two. God does exist and what we call aliens now, ancient civilizations called angels, demons, gods, etc.
When it comes to it, the fact is we don't know what's there and we probably won't know until we are dead. But I like to believe there are multiverses and different dimensions, and that psychedelic trips that are visualizations possibly similar to those when you die, which could lead you to believe that when people say angels, they mean the geometric patterns that you see when you are tripping balls. A higher state of consciousness. That seems more like a "heaven" to me than sitting on a cloud in human form, they just didn't have the language to describe it back then.
