As an agnostic (atheist in denial) i just dont know. I still struggle with why anything should exist. It's all too convenient. God just exists, he was, is and always will be. Who created God man!!! (pardon the atheistic pun) Same for the other side tho.... there was the big bang and suddenly time and space existed. Oh how very neat and tidy. So what made the big bang!!!
Anyway, the main reason is to ...... i couldnt resist sorry, is to quote Catch22 by Joseph Heller. It had to hapen some time. It's not a theological point....just it makes me laugh:
"And don't tell me God works in mysterious ways," Yossarian continued, hurtling on over her objection. "There's nothing so mysterious about it. He's not working at all. He's playing. Or else He's forgotten about us. That's the kind of God you people talk about - a country bumpkin, a clumsy, bungling, brainless, conceited, uncouth hayseed. Good God, how much reverence can you have for a Supreme Being who finds it necessary to include such phenomena as phlegm and tooth decay in His divine system of creation? What in the world was running through that warped, evil, scatalogical mind of His when He robbed old people of the power to control their bowel movements? Why in the world did He create pain?"
"Pain?" Lieutenant Scheisskopf's wife pounced upon the word victoriously. "Pain is a useful symptom. Pain is a warning to us of bodily dangers."
"And who created the dangers?" Yossarian demanded. He laughed caustically. "Oh, He was really being charitable to us when He gave us pain! Why couldn't He have used a doorbell instead to notify us, or one of His celestial choirs? Or a system of blue and red neon tubes right in the middle of each person's forehead. Any jukebox manufacturer worth his salt could of done that. Why couldn't He?".
"People would certainly look silly walking around with red neon tubes in the middle of their foreheads."
"They certainly look beautiful now writhing in agony or stupefied with morphine, don't they? What a colossal, immortal blunderer! When you consider the opportunity and power He had to really do a job, and then look at the stupid, ugly little mess He made of it instead, His sheer incompetence is almost staggering. It's obvious He never met a payroll. Why, no self-respecting businessman would hire a bungler like Him as even a shipping clerk!"
