Many say they are agnoctic, they do not know if there is a god or several gods. Often the same people separates themself from atheists as part of explaning why they say the are agnostics. But atheist and agnostics are not a scale to use.
To be agnostic has to do with knowing.
Do you know there is a god? Yes or no. If you don't know you are an agnoctic.
To be an atheist has to do with belief.
Do you believe in a god? Yes or no. If you don't believe you are an atheist.
There is a difference between knowning and believing. Don't act if there is not.
If you know there is a god. You are insane.
If you know there isn't a god, you possibly dos not understand the way of proving things. We can never disprove there isn't a god, a pink unicorn, Santa Claus/Father Christmas, a Flying Spaghetti Monster, Easter Bunny or, or, or, or ....
Don't use the them agnostic it has no meaning because we are all agnostics.
