And I wouldn't be going off on this tangent, but some of the definitions I have seen for this word are unfair and extremely biased.
Someone who doesn't believe in god.
Most respect others opinions and have EXTREMELY religious friends.
John the Faith-nut: "How did the universe happen?"
Stevie- "The big bang you idiot!"
John- "What caused that to happen?"
Stevie- "Definitely not god."
Stevie - "Who created god?"
(Nazi?) Atheist 1 -There is no god. We are all animals. Kill the Jew dogs.
Atheist 2-If humans aren't animals than what are we?
Faith nut-HUMANS AREN'T ANIMALS!
Faith nut-I'm gonna be pretentious and call Atheist communists while I'm the actual communist trying to abolish others beliefs for THOUSANDS OF YEARS!
Religious person: Atheist killed thousands!!!!!!!
Atheist-Stop making up facts. Wars are still going on about who's god is better and BILLIONS are dead. If god was real and had a plan for everyone than nobody would be atheists or have other religions. Please stop being an ignorant jerk.
Also, judging by the other definitions posted on here, they are people that come under a lot of flak from believers.
Its the atheist's choice really.
Existentially, they often believe that at the origin of the Universe there was nothing, and that nothing exploded - creating everything; before a bunch of everything magically rearranged itself, for no reason whatsoever, into inexplicably self-replicating parts, which eventually developed into intelligent beings with inexplicable (or at least incomprehensible) capacities for reason, ethical judgement and aesthetic awareness...
As Xenocrates stated; “Without proof, belief is still belief – even if you believe in nothing.”
