People have worshipped things that they dont understand from the beginning of our times, they have worshipped sun and one tribe even worshipped an large cliff that made an shadow looking like human head. How is this not understanding the beginning of universe any different from those? All are fundamentally just something we dont understand.
You know that people create their perception of the world, its not the actual world as it is that we are perceiving, but highly subjective world we see. But the funny thing is that we are not conscious about the subjectivity of our perceptions. We are the creators of the world, but its not th real world we create, its our own worlds we are creating, but arent aware that we are creating our world ourselves.
Projection is a normal human phenomena, it happens all the time, we even project to our visual fiel all the time. What you see right now is mostly your brains adding stuff to your vision, its not all coming from your eyes, and whats coming from your eyes, is very limited compared to whats actually infront of your eyes.
Now projection also comes in when filling the gaps that we dont CONSCIOUSLY understand and can even interfere with our vision if we believe hard enough(people seeing ghosts etc).
The source of our projections is our unconsciousness(memories, repressed thoughts, some claim oir unlived life, thoughts that have yet to get intense enough to brake the treshold of consciousness(and are waiting for a proper moment to erupt) etc). When we project, we see our unconscious self in others, things in your mind that arent intense enought to come into consciousness by itself, but is interfering with your cognition and perception.
On what REASON(belief to a man made book about belief is not a reason) do you say that this couldnt happen with the concept of god?
Where do religious visions come from(and most importantly, when they usually happen)?
Why is it that peoples belief on god varies so much? And how do you know that yours is the right one?
Whats the common thing about all religions?
I assume you believe in old/new testament. Did you know that these texts in it are coming from older religions and are modified and censored heavily(missing texts and stuff left out from texts)?
Do you know whats the origin of these texts? Why dont you believe in those original texts instead of man made collection/version of those texts?
How do you know that those original texts arent written to guide people to healthier more balanced life and is just a guideline for life and earth to be in balance, instead of an creator of universe?
If someone claimed that god appeared to him in a dream and said something, would you take that as a word of god? Would you think hes just nuts?
If not, why is it any different that this happened ages ago?
Why do i have an idea that you are unable to answer these questions?
If we wouldnt had weapons to protect ourselves from predators, we wouldnt had the opportunity to attack other tribes. You can see this in some other apes. They dont use weapons against each other, just to protect themselves from predators. They do things like climb on a cliff when a predator comes and throw rocks on it. Weapon is just a tool used to survive.
The fact that god is our unconsciousness isnt told in some bible book, but is something figured out by many people when looking at religions. Buddhism is basically about this, except they just dont use word unconsciousness. The aim of enlightment in buddhism is to come conscious of unconscious mind. The idea of enlightment is similar to all religion, its just that in religions like christianity the enlightment comes in the form of projections, but imo you cant even call that real enlightment.
I can even explain the concept of afterlife in neurological terms if you want to.
