You have to investigate what the stuff is, how it happens, and what happens as a consequence of it happening. When you do that, you learn more than by saying, "I'll never understand it so I reckon God done did it."
Just leave your next few dumb-dumbisms here, Tex, and I'll have a good laugh over them in the morning. Your Nobel Prize awaits.
Sleep well my fine feathered friend. Perhaps next time you and your fellow scientists get together, you could investigate why we developed a sense of humor and what caused the consequence we call "laughter"
I'll admit up front that I can't understand where it comes from but I reckon it makes a lot more sense to think that God gave us that ability than it came about because "stuff happens".
And, hey, one more thing. God loves you even if you don't give Him credit for all this beautiful and wonderful stuff he gave you to rack (wrack?) your brain over.
