Why agnostic? Like… If there’s no proof, why believe in the existence of a deity at all?
For me personally, atheism is saying ‘there is nothing more to the universe or reality, what you see is what you get’ which is extremely pretentious. Agnosticism is admitting to the possibility that there’s something going on here, but we don’t know and would likely be incapable of understanding what it is.

Atheism: I don’t believe in the existence of god(s)

Agnosticism: I haven’t seen any proof for god thus can’t believe in one

It’s the same thing really, but without the “negative” connotations usually attributed to atheism or atheists

“See, I’m not really an atheist but agnostic. It means I’m not to be expelled from this community as a heretic”

I identity with this. When I was younger I identified as agnostic, as I saw it as a more socially acceptable option than atheism which allowed me to not have to pretend to be religious.

But I’ve identified as atheist for many years now. In my case by the time I did, everyone of significance in my life was nonreligious.
