I've used this argument -- it is really more a puzzle, perhaps even a proof -- many times before. I have used it on the web several times; and it played a central role in Part 1 of a book I wrote (still no publisher). In April, it appeared in an exchange I had with atheist-novitiate Luke Buckham at his blog, O Machine.
I thought that some of you would find it fun, though some of you may find it frustrating. Those of my readers given to debates about theism might find it helpful, for it "proves" a very serious thing. I'll let you read for yourself what that thing is.]
[UPDATE, 12.5.07: Because what follows was originally drafted as a comment -- submitted in a discussion elsewhere -- it was hastily written and edited. As a result of some confusion, and some of my own disappointments with the piece, I am emending it to more closely resemble a well-written essay. Thanks. BG]
FOR FUN: THE SPEED OF LIGHT AND YOUR EXISTENCE
Let me note this: If the speed of light is finite, and yet it is the "fastest thing" (186,000 miles/sec) in the universe, then it follows that there is no present, there is no "present tense." Every perception MUST be delayed; we only know the past, irrespective of how quickly light reaches our eyes. From object to eyeball, from fingertip to wine glass, there is a delay; even the body's neurology operates at a finite speed. Hence, we only know a present by inference; but such an inference is rooted in faith. †
Let me go with this further. If the speed of light is finite,†º then know that when you look at the stars in the night sky over Wisconsin none of those stars "exists." Only their light "exists;" their fiery furnaces may have gone out long ago. Every single one of them may be gone, burnt out and dead in some distant explosion or some crushing implosion. We CANNOT "know" they are there, we can only know that they once were there, or so we induce from the light we see.
Now, go with me even further. All your life light has been bouncing off of you, traveling about the earth. Imagine for a moment that the light from your skin travels out from the earth and into space. Assuming that you are only about 40-years-old, then you are, in a very real sense, 40-light-years old, too. What does this mean? It means at least this: to the overwhelming majority of the universe, YOU DO NOT EXIST. Anyone 100 light-years away CANNOT know you exist. But, and here's the rub -- YOU DO EXIST. So, alas, we have a problem: Most of the universe cannot even know that life on earth exists -- and yet it does. Nearly every quadrant of the universe could never -- ever -- be shown ANY evidence of your existence, and yet you are in fact a very real being. What does this say about our sense of knowledge? What does this say about our demands for proofs for the existence of God? For if you exist and yet the universe cannot and does not "know" it, then perhaps God exists and you cannot know it -- or do not know it -- yet.
Surely I can at least make this concession: if it is extremely hard for me to prove my own existence to myself,† and if it is hard for me to prove my existence to you, then surely it would be hard for me to prove God's existence at all.
But you do ask for "proof " for God's existence, and I have none. But what if I said that the sun is God? You might counter that the sun is nothing more than a fusion reactor where the helium atom is smashed about. But what if I said this: How do you know God is not a fusion reactor? How do you know God is not a big ball of gas? What I am saying is that just because science has "explained something," it does not follow that science has not described the evidence which points to God; a thing explained is NOT God explained away. God may be proved by my pointing to a prairie dog. How do you know that such evidence is not evidence?
†[To explore this further, please see my essay, "A Letter to Christopher Hitchens;" therein I examine the impossibility of the self proving its existence -- to itself. The main examination occurs following the sub-head, The Transcendental Ego.]
†º[It should be noted that if the speed of light is instantaneous, then there is no delay except that between our senses and our perception. But let's assume that there is no delay even here. With that said, light that is instantaneous removes from us the ability to determine the age of the universe.]

I would like very much to thank Chris from "Sorry We're Open" for his kind support and many encouraging words over the last several days. He particularly liked this "proof," and so I felt obliged to share it with the rest of you. If you hate what I've written, well, then direct your ire at Chris. Of course, I jest. But I'd surely love to know what you think.

This New York Times piece by physicist Paul Davies is interesting -- especially if you draw your worldview from science. See? Faith is not so bad.
