How each person defines Agnostic and Atheist for themselves is determined by their own experiences and knowledge. We all have a life story and no one has the authority to define it for us.

For me:
Agnostic means no solid belief about the whether deities exist or not.
Atheist means no solid belief in any deities at this time.
Theist mean a solid belief in one or more deities.

I'm both agnostic and atheist. The difference in the terms is subtle, but I don't claim to know whether there are gods or some creative source that we just haven't discovered yet, but I don't live under the rule of any god at this time.

I surely don't live under the rule of the Biblical gods, Roman/Greek gods, Norse gods, etc. I'm of the mind they are all mythological gods. Only true for the telling of a story.

While I love the idea of metaphor and story telling to help us understand aspects of life, I am not of the mind to go "all in" with total literal belief in any of them.

It's fun to imagine the various scenarios and perhaps moral lessons in the stories, as long as we realize they are just stories, not history. I'm not of the mind to think that was actually ever the intent of any of the mythologies we know about from the ages. It's wise to learn about them and how they mirrored and affected the cultures for which they were intended.

Mythologies have their place along with actual history, education and scientific exploration, but we should not lose our humanity with any of them. We do have wonderful human qualities (along with some selfish ones) and learning to coexist with other humans usually comes from civil laws, society norms, common sense and etiquette, far more than religion.

One thing I know for sure, is that the current common religions were created for a different time and place and have no relevance in our immediate culture.

I have come to realize that I don't know anything. But I know what I believe & I don't believe in deities. I am comfortable in not having the answers to unanswered questions. I am a dolt in the great universe of universes.

This back and forth of these terms definitions keeps going. I know a deity does not exist and that is all that matters.

You can be both atheist and agnostic…they are not mutually exclusive. I am both…atheist because I can’t say I believe something without evidence…agnostic because I do not know if evidence exists, but I am willing and open to believe if any credible evidence is found.
