Atheists!! What is the source of Atheism.. according to you..?

Everyone is born ignorant of all realities, including the reality of God. As we grow older, we discover one reality after another. Most of us discover the reality of God. Some of us don't, which is why atheism exists. Of course, some atheists do discover this reality every year, becoming Christians.

The source of atheism is the simple fact that there is absolutely no verifiable evidence that any gods exist.

Atheists are deceived by the devil into believing God doesn't exist.  The devil often successfully deceives the intellectually proud and those who do not pray very much.

The lack of gods. 

What is the source of awoozleism?  The lack of woozles. 

I mean, even the term god is so meaningless because it is whatever is left over when you have exhausted explaining away your original definition. 

Never being brainwashed in the first place, and being of a reasonable intelligence.

The source of my atheism is the total absence of any evidence to prove the existence of any gods. Religions are the construct of men who sort power.

Atheists don't believe in gods. 

That's easy.

Reality.

What you're asking for is a source for belief in something that particular people don't believe in. Which doesn't really make sense. They're happy for you to worship God, Odin, Pan or volcano deities if that's your preference. An atheist simply doesn't believe that your God exists, but I'm sure most would happily change their mind if said deity were to prove the actuality of his or her self.

The source of atheism is no longer needing any placeholder explanations and resorting to mere speculation to fill in the gaps. Science has become increasingly able to explain what's actually going on due to advances in technology and understanding of scientific processes.

We no longer need to wonder what, for example, makes the Sun appear to move across the sky since science figured that one out, we KNOW. No, it's not Apollo moving in a chariot across the sky that's pulled by fiery horses, it's a star.
