A person who does not believe in God. Claims their belief is based on logic and rationalism, but is really just a lack of an answer for why the universe exists, what caused the creation of the universe, or how the laws of science came to be or why they are consistent.
The most tolerable atheists just
don't talk about the matter at all, and the worst atheists spend all
day insulting religion in general on the
internet.
Essentially, a person who is not thinking but believes he is the only
one who is.
Atheist: At first, there was
nothing. And because there was
nothing, nothing happened, and then
nothing occurred and then the universe appeared. It's the only explanation that makes sense!
Theist: You keep telling yourself that.
