1. No, because first this idea was presented by religious zealots, which is a group of people I think are idiots. Secondly, I don't believe it because the bible itself contradicts this "prediction", multiple passages elude to the date being unpredictable.
2. I know for a fact that if the world ends then, and in the way Christians are thinking, I'm going to hell without a doubt; so I'll be raping, murdering and enjoying myself in most hedonistic of ways possible.
Honestly, once the day ends, I'm going to be laughing at all those who believed the idea and say that faith caused them to make a fool of themselves and persuade them to look into atheism.
