Why take the philosophical route of "why does god allow evil if he exists?"
Just cut to the chase.W're all born without a belief in god.God can't be proven.No equation predicts its existence.Therefore,there's no reason to start believing anyway.
You greatly underestimate the visual cortex.
If you were to ask a dog to describe the world, it would be in 3 colors.
Attempting to determine what exists based merely on what
you can perceive is inherently flawed.
Until you unlock your brain and stop seeing with your eyes, you will have a highly limited understanding of the world.
The majority of people, almost 100%, even high level scholars and scientists, still see with their eyes despite understanding that they can bypass the eyes and see directly with the visual cortex.
So humans as a whole are not well equiped to discuss what is and isnt there.
They don't even use the tools they were born with.
Animals that willingly clip their own claws and toil for currency are too far removed to understand much of anything, in my opinion.
There are things 99.999% of people will never see that they can access right now, like impossible colors. They simply lack the understanding. But without understanding truesight via the visual cortex you have 0 chance to see god or anything else 'otherworldly'
