Evolutionary psychologist Donald Hoffman presented the Interface Theory of Perception. He argues that our senses and consciousness did not evolve to show us truth; they evolved to help us survive.
Arguably, surviving needs truth. I mean you need the truth that there are predators out there for example. But truths such as God if he exists or Jesus being the Son of God - if they are truths - are not the same.
If consciousness didn't "mask" what it actually is, our attention would be constantly diverted inward, analyzing our own neural wiring instead of scanning the horizon for data, food, or threats. By hiding its true mechanism behind a seamless curtain, consciousness ensures our attention is always diverted or projected outward onto the data that matters most.
The mask is why it feels so non-material.
We get a reward from taking something as spiritual or non-material - we think it is going out somehow outlast the dangers of the material world. That is why our spiritual ideas arouse suspicion in those who listen to us.
Also if there is too much wishing and feeling involved, we will dress it up as some kind of spiritual intuition to avoid looking ridiculous.
Consider the eye. It works because of mistakes - that word will have to do - in how it is produced. Similarly, consciousness depends on a lie or error to work well. It is not a spirit in the image of an honest God.
I experience that I am aware and that it feels like some kind of miracle among the mundane - some kind of ability to be bigger than the body or brain. Then I decide that there could be a divine conscious being. Projection is inevitable. The God is really going to be just my mirror - my placeholder for things that are in me and about me.
I am a body and if I am conscious that does not mean a
conscious being can exist without a body
