I'm an atheist, my wife's a Jehovah's Witness. Each of us knocks on your door and has something to sell to you. It's up to you to choose. Take one, take the other, take neither.
1. There is no god. We can't really be expected to understand much, that's how primitive we are, but it appears from the evidence (if all those scientists can be beleived) that we are animals like all the other animals around us, only we're smarter. A billion years ago, life generated spontaneously as a self-replicating molecule, natural selection took over and the rest is history. And, by the way, you're gonna die.
2. There is certainly a God, and his name is Jehovah. He created us, and all the other living creatures around us. And He did it, not over the course of a billion years, but scant thousands of years ago. He made us, and all the other living things in the world. We, his most beautiful physical creation, then betrayed Him and He cursed us. We were innocent and pure as the driven snow, as we were when He made us, but we should have known better. This snake shows up that's different. This snake talks, and he convinces naiive Eve (she's just part of a mere rib of a man, after all) to take a bite out of a fruit she's been forbidden to taste by her Creator who had said, like, just yesterday, "Hey, you can have eternal life exactly the same way as you have it now, forever and ever, for all eternity, living here in the garden with Adam, making kids, eating fruit, petting lions, over and over again, for all time neverending." So, somehow Eve decided the prospect was not enticing so she bit into the fruit, knowing full well that she'd be inviting down on her head and all of humankind the wrath of Jehovah. Well, Jehovah was indeed some pissed, and he cursed humankind. But he made sure we survived. He made sure we would endure through a Great Flood so that we might survive and repopulate the world. He guided us through the wilderness and found us a home. He brought forth the human saviour who would atone for the sins of our original parents (the ones sucked in by the snake) and He set him up to be a blood sacrifice in the most horrific manner conceivable just so that we might live forever. And all you've got to do is believe it, and you'll live forever.
Which one do you buy?
