I find it odd that as a people we are obsessed with our own destruction. This guy has gone to a lot of trouble to say that 23rd sept marks the beginning of the end. Its not even a religious thing, how many times has it been reported such and such asteroid may hit us. We delight in our own misery, planning for nuclear, astronomic religious viral or even zombie apocalypse. Are some peoples lives so bad they waste it preparing for the unknown and unlikely?
Whether you're religious or not, live your life to its fullest enjoyment and try and do it with no regrets without hurting others, and if there is a God, at least you've been a good person. If not, you can reflect on your death bed with fondness of a life well lived.
That said, I've stuffed up the hurting others part, and when the zombies come you're all welcome to my bunker.
