Cant really say I ever truly believed in god to begin with. My mom has gone to church on and off since baptizing me and dragged me along. Never understood the sermons so I basically just went to sleep until she started sending me to the kids daycare the church had, where we just watched Veggie Tales all the time.
I viewed god much the same way I viewed Santa Claus. I asked santa for something specific and within reason but never got it. I prayed to god for help when my mom said someone she knew randomly got shot and ended up not making it. Must have been just another story.
It has only been in recent years where I have seen the arguments for and against god on the internet. The arguments for god never really make any sense, and when they do make some kind of sense, they dont entirely match up with the bible, which in itself doesnt seem to be a source of knowledge.
The arguments against god however, which usually pick apart the bible and show the blatant contradictions and overall immorality of the bible, usually make plenty of sense.
I have come to the conclusion that Christianity's god does not exist, nor do any of the other gods of the major religions of today. I am open to the possibility that no god exists, or that some non specific god who doesnt actually intervene with day to day life could exist (not deism exactly).
Hence my label as an agnostic atheist. Its actually very recently that I have even considered myself an atheist of any sort, but even after explaining my stance on things I am continually told that I secretly believe in god and wish to be saved because I point out flaws in believer's logic.
An interesting cycle, to say the least.
