Every dog has it's day.
Anyways, the only reason I tell Christians that is because they don't want to discuss religion but tell me Islam is wrong and Jesus is the only, if I don't want to go to hell. So I simply tell them why I don't believe in Christianity. They don't want to discuss, just sell Christianity. so by say no, we both save time.
There is no heaven or hell, there is no guy in the sky that knows all, see's all, hears all, and loves you for banging your head on the ground five times a day and not eating pork. Try to wrap your head around that fact. When you die you are either going into the cold damp ground or up in smoke, that is the.......... end..........there ain't no more, no second chance. Try to enjoy each and every day that you can because life is very, very short. Don't waste it on bullshit!
