“It’s call themselves. They set themselves up as their own god and decide what will happened once they die.”
Lets see: 1. I don’t worship myself. 2. I don’t claim to be omnipotent.
“Their knowledge is limited to what they see/hear”
That’s what knowledge is. It’s knowledge based on reality and is belief-neutral. Atheists, Christians, Muslims, Jews, Hindus, etc. who repeat the same experiment will get the same results.
You cannot know the things of God in your natural state - limited to what you see/hear. Do you believe you have a soul and a spirit? If so, where did that knowledge come from? Some worship there body and never give one thought to their spirit and it's the spirit that never dies - it will go someplace for eternity. Some put trust in only what they see.
There is a big difference between believing there is a God - natural senses in play - and belief in God which equates to His Word reigns, He's All Knowing - faith in play.
