I follow several atheist YouTubers. The growing consensus among these atheists is to define an atheist as "a persons who does not find sufficient evidence to foster a belief in a god or gods." This is where I find myself. That is to say, "I do not find there is sufficient evidence that there is a god, but if someone finds evidence to the contrary I will have to accept it and adjust my thinking."
When I finally came to the conclusion that Jehovah's Witnesses are not the true religion I became an atheist in a heartbeat. One second I was a believer and the next I was not. I went right to antitheist. Not only did I not believe, I had a general dislike of all religion and actively put religion down. The problem with me was I became nihilistic and that generated a lot of suffering in me and, by me, a lot of suffering in those around me.
I started becoming religious, even Christian, again. However, it didn't take too long and I began to see right through all Judeo-Christian belief. I discovered that a large part of the Bible was myth. Even that which many believe is historical never happened. Not too mention I was disturbed with just how bloodthirsty YHWY is and David praying for YHWY to kill his enemies and grant him victory in battle was the final nail in the coffin for me.
It is hard to believe how many people, educated people, still believe the Jewish mythology of Israel being a special people. That at one time there was a nation of Israel that was enslaved by Egypt and that a man named Moses lead them to freedom after talking to a burning bush. That this nation wandered a desert wilderness for 40 years while making animal sacrifices to atone for their sins. Outside the Bible, there is no historical or archeological evidence that supports this. Even the existence of kings Saul and David are questioned.
If the Old Testament is all a manufactured myth to make a Canaanite tribe feel special after being conquered by the Persians, how can anyone believe in Jesus being the Messiah? Christianity's foundation is the fulfillment of a Jewish Old Testament prophecy. If that prophecy is a myth then Christianity is founded on a myth.
