Here is the thing. I am an atheist. I know God does not exist. I see a lot of evidence that God is a man-made concept, idea, or personification of life that logically explains the purpose of our existence to people who use this to help them in life.
I also know that, because no God exist, theist can only make a claim not a certainty. What makes me so curious is that some theist do not agree that what they say are claims, beliefs, and faith but instead, say they are fact and truth. If a theist can say what they believe is not truth in general; that, would be rare.
Also, because no God exists, of course, the default would be nothing. If I have no pencil in my hand until I claim one is in my hand, my hand will be empty. Once I make a claim that a pencil is in my hand (although empty), any other atheist can disprove it all they want. What they are doing is disproving "claims, ideas, theories, and stories." They are not disproving a fact. There is no pencil. You can't disprove nothing. It is a default before anyone can claim or give me a literal pencil.
So, if there is a God then atheist have a logical reason to disprove or "dis'belief'" in whatever the theist claims. Until then, it's all empty. I was just curious if people know God exist or doesn't exist compared to others who say they believe they know or don't know. The former pair does not leave room for anything to exist. The latter pair, it does regardless of belief.
