Tell me, 2LifeGuy, do you think Adam was physically strong? I don't mean super-strong or anything, just reasonably buff, like a young adult today who works out three days a week at a gym? Do you think he was dextrous, good with his hands? Do you think he was clever, good at solving problems, brave, resourceful? Could he run reasonably fast? Did he have good eyesight? Good endurance? Did he have a good immune system? Would a young woman from today (post-Fall) likely find him attractive?
If your answer to any of these is no, then you'd have to explain to me how the "genetic degredation" or "effects of entropy" Creationists usually say happened after, and as a result of, the fall led to the development of these improved qualities. But I rather suspect your answer will be yes.
Assuming your answer is yes, then I ask: why?
There was no strife in Eden, so Adam had no need to be strong or fast. There was no need for toil, so Adam had no need of strength or endurance. There were no problems to solve or dangers to face, so Adam had no need of resourcefulness, courage, or really, any intelligence at all. There was no disease, so he had no need of an immune system. Sex was not supposed to be necessary, so Adam had no reason to be physically attractive to a woman.
In fact, there was only one thing that Adam was required to do in Eden, which was obey. And he didn't do that very well, did he?
So, if Adam was designed, it was the stupidest design in the history of design. He was designed to be able to do a whole bunch of things that he wasn't supposed to ever have to do, and the one thing he was supposed to have to do, he wasn't designed well enough to accomplish.
Looking at the "degenerated" descendents of Adam and Eve, it certainly doesn't appear that humans were designed to live in a garden free of trouble, danger, and toil. Strong maneuverable forelimbs, opposable thumbs, binocular vision, clever minds good at inventing new things, immune systems, robust omnivorous digestive systems, and countless other features indicate that we were well-designed to survive in the natural world.
Which is exactly how one would expect humans to be, if we were in fact "designed" by evolution.
So take your pick: either God designed humans all wrong as described literally in Genesis and is clearly inept; God designed humans well but Genesis lies to us about what we were really designed for; God designed humans to live in a garden but humans got a lot stronger, smarter, braver, faster, nimbler, and more capable after the Fall (by evolution, perhaps?), or God created humans by evolution in the first place and Genesis is allegory.
