Proof of God's Existence?
Strong Evidences for God's Existence
So you want "proof" of God's existence? Not found here, but I'll give you some pretty sound evidences:
I am always drawn like a magnet to science and biological topics. One day I became aware of something in the human eyeball that is called the "fovea." The fovea is a small depression about 1/2 to 1 millimeter wide at the back of the eye, situated on the natural line of sight from the lens. This area is depressed, because of the absence of several things, such as blood vessels, rods, and other cells. The unique thing about this curious aberration is that it helps us to see detail.
Covering the back half of the inner eye is the retina. It is full of blood vessels, rods and cones, and supporting cells. One thing about it, though, is that the rods and cones are at the back of this layer. In other words, light and images we see have to pass through all the other material first, before arriving at these visual receptors. The result? Less visual acuity. But where this depression is -- the fovea -- these materials move aside to let images coming through the lens go directly to the cones, the cells that interpret color. In addition, there's an extra helping of cones. Hence, we see rich detail.
I got to thinking about this phenomenon, wondering how something like this could evolve on its own, or through the process of natural selection. Then, after it was a finely-perfected machine, I wondered how the genes knew where to place this fovea. What are the chances that it was first placed conveniently at the back of the eyeball, and how long would it take, through natural selection, to find its way to the back? In fact, how could "natural selection" play a role in this type of evolution? The existence of the fovea seems to be the result of a complex cooperation of elements all at the same spot: first, a motive for its existence; next, its position in the line of sight; the fact that it occurred in the eyeball; the absence of blood vessels, rods and other materials; its shape; the increased number of cones (50% of the information processed by the optic nerve comes from the fovea, while the rest of the retina supplies the other 50%).
Recently, I voiced these thoughts while visiting my eye doctor: I pointed to his poster on the wall that showed a cross-section of the human eye, asking about the fovea. His response: "The more you get into molecular biology, the more you have to accept the idea that there has to be some kind of "intelligent design." (This doctor, if you need references, is with the Moran Eye Center at the University of Utah.)
Here's another phenomenon that scientists cannot explain, but only attribute it to "some kind of intelligence:"
To the side of the fovea is the optic nerve. Visual acuity is impossible at the point where the nerve leaves the eyeball as it connects to the brain. The reason we can see things in that spot, though, is because the optic nerve of each eye is offset at opposing angles to the line of sight. So one eye (or, better said, that area of the brain) will make up for what the other eye (area of the brain) doesn't see.
To find your blind spot, refer to the "Blind Spot Test Image" above. Place yourself 8 to 10 inches away from the image. Close your right eye, and look at the top line of characters. Scan the letters back and forth until the dot to the left disappears. Adjust your distance from the image until the dot disappears while you are looking at the letter "E." When you look to the left of the E, you will see the dot. When you look to the right of the E, you will again see the dot, indicating that it has not left your peripheral vision, but that you've encountered your optic nerve blind spot. The second line is for your other eye.
The phenomenon I'm referring to is that when you ceased to see the dot, the area wasn't filled with blackness, like what blind people see. If you do this same test on the white lines, the blind spot will now change from "white" to "black." If you were to test this on a colored background, the blind spot would turn the color of the background. On a background of various patterns, you would not notice a break in those patterns. If you were to hold up a pen in the vertical position, it may not even seem to disappear from view, probably because of this same compensation the brain seems to supply: as the top and bottom halves of the pen are not blocked out, then the brain makes up for what's in the blind spot, even with just one eye! If you were to hold the pen toward you so that it became just a dot, it would disappear. But by putting it vertically, while maintaining your distance, the whole thing reappears.
One more thing about what we see: How were "cones" made naturally, so that we can see colors? How did they coordinate their data-gathering capability with the brain, to help us see those colors? Weren't the rods -- the black-and-white receptors -- sufficient to help us see things in our environment that would be necessary for our survival? If you can answer that scientifically, my hat comes off to you, and I'll send you a dozen cookies, or roses, whichever you prefer (only the first three successful participants will be rewarded).
These are only a few things of many that tell me there is something more out there than what the eye can see. If people want "proof" that God -- or "intelligent design" is out there, I think this comes the closest. Of course, the existence of a god cannot be "proven" scientifically at this point in time, but I think this is one of the strongest and most irrefutable of evidences.
