Rock Balancing & Intelligent Design
How's this for cool art: Bill Dan balances rocks. Take a few minutes and browse his site - some very cool pictures there (although the image quality is a bit grainy on some).
Now ask yourself this - how is it that you can see a picture like this and intuitively tell that it was created; that it didn't just happen? I suspect that just about every single person who sees this image naturally recognizes the hand of an artist, a creative mind - there is symmetry, there is beauty, there is a sense of humor. In short, there is evidence of design.
You see it, you know it, but you would have a heck of a time trying to prove it (or disprove it) scientifically. Because science can tell you the way something is, the way it behaves, but it cannot tell you what something means.
Nevertheless, we can't be help but perceive meaning. Because God designed us that way - God as creator has created us, both to be creative ourselves, but also to recognize the hand of the creator when we see it.
Anyone who spends a little time looking at nature with eyes to see can tell that something more than happenstance is going on there; yet we try and deny it because we have a vested interest in there not being a master designer. Scripture says all creation cries out, and we do hear; the only way around the truth is to suppress it.
I think this is at the bottom of what the Intelligent Design folks are trying to get at (well, some of them any way).
