I will not tell you that there is no God, or deities, or paranormal, or supernatural; or even a spirit realm that is distinct from the physical realm.
I will only ask you...
What is there to perceive that is outside of your five senses and mind?
If it is a possibility to know what is beyond the senses, you must get rid of your senses.
But no one is ready to do that; don't worry, it is unnecessary to do.
Using your sense perception, you create everything in this universe.
