None of the other claims of knowing: knowing God exist, knowing Allah exists or knowing the computer screen exists claim it is necessary to know everything in order to stand up logically. The person who says God doesn't exist must, logically, know everything meaning they are God.
A few points to make:
1) Knowing everything does not make you God.
2) When you describe 'knowing' as this:
quote:
Knowing something does not mean that actually is the case. Not my knowing God exists, nor a Muslim knowing Allah exists, nor you knowing there is a computer screen on front of you.
Knowing is the best anyone can say regarding their own certainty. The highest court in anyones land. But that doesn't mean a thing if the objective reality one resides in is not in fact objective. Which of us is deluded, you, the muslim, me. There is no way to tell for any of us (unless of course God exists - then we are not reliant on our assumptions about reality. He can overcome them - being God)
Lets not put knowing above its station huh?
then you wouldn't have to know
everything to claim that station of knowledge. So I still don't see how they are different. And it still seems like you are using diferent definitions of 'know' for knowing god exists versus knowing he doesn't.
3) With an accepted defnition of knowing something, you wouldn't have to know
everything to 'know', by your defintion, that god doesn't exist.
Does knowing that god doesn't exist require you to know the 145 digit in the number pi, or what I had for lunch yesterday, or what Homer Simpson's last line in episode 92 was? Why would you have to know these things to 'know' that god doesn't exist?
