Are there any scientific grounds for god? This is the crux of it for me. Think of it like trying to explain yellow to someone who is blind. You can kind of attempt do it, by way of references to other senses.
I think it is quite reasonable to understand that people have different experiences and, furthermore, that some people have had some quite powerful experiences that many others have not. These more unique experiences are ‘feel more real than real,’ even though that turn if phrase sounds strange in and of itself. I cannot explain what it is other than to refer to it as a vivid sensation that feels like a transition from a 2D cinematic experience to a fully fleshed out 3D theatre experience. One is far more ‘present’ than the other, more ‘connected’.
If you have had an episode of psychosis you probably understand this a little. When, for instance, people talk about ‘hearing voices’ but the ‘sane’ person would say ‘of course I would understand it was in my head’ but you likely wouldn’t as the voice you hear sounds like it is ‘outside’ and acts as if completely independent from your own conscious thoughts.
This is why I generally think of the whole god/religion concept as something entangled within the human psyche. The ‘space’ between unconscious processes and conscious thought. The interesting thing is there is a common pattern to how such things present themselves as ‘independent beings’. Studies with DMT have shown some fairly strong reported instances from both religiously inclined and non-religiously inclined people. For myself personally I believe what happens is the human brain can naturally produce DMT and the effect of this on conscious is the reason ‘religious experiences’ exist.
If the above is correct then a further problem is understanding what kind of stress the human body has to go through to natural produce enough DMT to induce such profound experiences. DMT has been found in a rats brain, but last I looked there was still no direct evidence that DMT is naturally produced in the human brain let alone in large enough quantities to be of significance.
There was a woman who had a stroke (forgot her name). She was also a cognitive neuroscientist. She describes a ‘connectedness’ and sense of bliss I can relate to. The potential for such experiences is both scary and inspiring in terms of human development. If myself, or the woman here, had been brought up in a religious manner then I can completely understand having a solid and unshakable ‘belief’ in god there after. My upbringing was about as secular as can be so I didn’t end up preaching on the streets. There is little doubt in my mind though that many religious figures experienced something akin to what we both did and tried damn hard to square it and express because they fully understand how powerful the experience was and potential of humanity.
