For those who say {There Is No God}
What the people that make this claim fail to realise that this is logically impossible.
Allow me to explain: "I know there is no God" or simply "There is no God" are absolute statements. For those statements to be true the speaker would have to have absolutely all knowledge of all evidences, everywhere for all time, which of course if they are being honest they will admit they do not possess.
So, since they cannot in reality claim that they know that there is no God, then the more truthful statement should be, "I do not at present know whether God exists or not."
While this irrefutable logic doesn't conclusively prove God's existence, it does disprove the categorical denial of the existence of God! and thereby existence of atheists (in the strictest sense) for as I have shown they must be agnostic!
