Atheist and Agnostic

[Freebird4077]

What exactly is the difference?

Atheism-
1: the doctrine or belief that there is no God
2: a lack of belief in the existence of God or gods

Agnostic-
1: uncertain of all claims to knowledge
2: a person who doubts truth of religion

Not again D:
This is one discussion we can't get rid of.

Agnosticism is, like what you posted, a claim about knowledge and not about belief. So you can very well be atheist and not believe God/s exist, but also be somewhat agnostic in your attitude about that knowledge. You can believe there are no Gods and think it very improbable that any could possibly exist, and still leave room for doubt. It overlaps a lot, and can go with theism too. You can believe in a God and not make claim to that absolute knowledge.

There are so many different variations of what atheists and agnostics believe. There isn't any set rule there. Some atheists will feel much more strongly about whether they 'know' no God exists and some agnostics will feel different about whether it's possible for humans to make any claim to that kind of knowledge in the first place.
People can call themselves whatever they want though.

This should be helpful on the different kinds of Non-Theistic beliefs but research for yourself. This is a small view on non theistic belief system there is sooo much more
