First line of wikipedia:
Atheism is, in a broad sense, the rejection of belief in the existence of deities.
There are of course 2 kinds: Moderate is the lack of a belief.
Strong Atheists assert that "at least one deity exists" is a false statement.
Since agnosticism is very similar to atheism, the 2 categories are often grouped. Since agnostics lack a belief, they are technically atheist.
Are you Atheist? Which type are you?
Also, are you naturally skeptical? I have this silly idea that most atheists would be skeptical in all aspects of their life.
I'm the apatheistic type where I don't care about the question of the existence of deities and live my life not worrying about the question. Or other metaphysical entities, I'm sure we all know a few, chubacabra, lizard people, ghosts.
