Tell me something. Are these the same question?
"Is it possible to time travel?"
"Has time travel ever occurred?"
Are those different questions to you, or are they the same?
Atheists do not believe in a god. However, that does not mean they claim to know if one exists. They just have no compelling reason to believe in any of the proposed gods at this time.
An agnostic does not know if KNOWLEDGE of a god is possible to acquire.
Do you see how that is a different subject altogether?
Are you going to answer my question?
This whole thing goes back to divisions within:
The question is about knowledge versus belief. "I've never seen a reason to believe there are deities," versus, "I have evidence that there are no deities." Same with the religious folks and faith versus knowledge.
I do not understand why theists keep trying to define atheism to atheists.
