Personally, I'm an atheist because I see no credible or factual evidence that any gods exist. Plus, it's obvious that the authors of the bible were very superstitious, backwards men, and there's so much of the bible that is false that it's not worth putting any belief into any of it. Lastly, there's no independent evidence outside of the bible which shows that Jesus actually existed as the stories in the bible state, and even if he did, he told his disciples that he would return and the end of the world would occur in their lifetimes.
Christian apologetics is the art of rolling a dog turd in sugar and selling it as a donut.
