Evolution of the Eye:
When evolution skeptics want to attack Darwin's theory, they often point to the human eye. How could something so complex, they argue, have developed through random mutations and natural selection, even over millions of years?
If evolution occurs through gradations, the critics say, how could it have created the separate parts of the eye -- the lens, the retina, the pupil, and so forth -- since none of these structures by themselves would make vision possible? In other words, what good is five percent of an eye?
Darwin acknowledged from the start that the eye would be a difficult case for his new theory to explain. Difficult, but not impossible. Scientists have come up with scenarios through which the first eye-like structure, a light-sensitive pigmented spot on the skin, could have gone through changes and complexities to form the human eye, with its many parts and astounding abilities.
Through natural selection, different types of eyes have emerged in evolutionary history -- and the human eye isn't even the best one, from some standpoints. Because blood vessels run across the surface of the retina instead of beneath it, it's easy for the vessels to proliferate or leak and impair vision. So, the evolution theorists say, the anti-evolution argument that life was created by an "intelligent designer" doesn't hold water: If God or some other omnipotent force was responsible for the human eye, it was something of a botched design.
Biologists use the range of less complex light sensitive structures that exist in living species today to hypothesize the various evolutionary stages eyes may have gone through.
Here's how some scientists think some eyes may have evolved: The simple light-sensitive spot on the skin of some ancestral creature gave it some tiny survival advantage, perhaps allowing it to evade a predator. Random changes then created a depression in the light-sensitive patch, a deepening pit that made "vision" a little sharper. At the same time, the pit's opening gradually narrowed, so light entered through a small aperture, like a pinhole camera.
Every change had to confer a survival advantage, no matter how slight. Eventually, the light-sensitive spot evolved into a retina, the layer of cells and pigment at the back of the human eye. Over time a lens formed at the front of the eye. It could have arisen as a double-layered transparent tissue containing increasing amounts of liquid that gave it the convex curvature of the human eye.
In fact, eyes corresponding to every stage in this sequence have been found in existing living species. The existence of this range of less complex light-sensitive structures supports scientists' hypotheses about how complex eyes like ours could evolve. The first animals with anything resembling an eye lived about 550 million years ago. And, according to one scientist's calculations, only 364,000 years would have been needed for a camera-like eye to evolve from a light-sensitive patch.

I really like your watermark analogy, I would like to extrapolate on that. First, you are right, there is only faith as yet for evidence. But, as we know, there is an awful lot of it. Picture it covering the earth, like a network, or a web of belief. Now hold it up to the light, you will see the watermark. I truly believe this to be the incontrovertible evidence of God's power. I see, though, that I have not offered what you have requested. This is not empirical evidence that "one specific entity" has "made the universe, or created existence". This is definitely not something that "can't be explained by some other phenomenon". I definitely acknowledge that this might not be '"seen as a rational and agreeable explanation by the majority of intelligent humans" LOL! So, I agree with you...there is not empirical evidence...Yet! Thank you Free Thinking American!

how does the universe and earth give proof of god? it gives proof of life not god. there is nothing to prove the existence of god that why they say u need faith. u cant prove the universe was created by god, u cant prove we didn evolve, if u could then it would be a world known fact that god exists. no one knows how we are here and why, and thats why god "does exist" because people have no other explination. and if god created an infinate universe and all of the planets in the universe why would we be the only life form? and better yet who/what created god? i will tell you who, the human race created god when the cavemen were sitting around a campfire. god is the biggest believed rumor ever told, its like santa claus, except people actually think he is real. if i could go back in time i would completely eliminate the bible from history, because all of this "prescious" religion and belief in god does is cause un-nescessary wars over whos beliefs are right and whose are wrong. what a god, to lead people believing in different things and ultimatly ending in pain, suffering and death.

Great question! If we need faith and there can be no evidence to support that faith, then any intelligently designed thing is evidence and contradictory. On the other hand, ID as evidence shows that evidence should exist in the physical world, therefore there should be supporting evidence for the miracles in the Bible -- which there is none.

When I look at the Universe, the beauty of the world - Flowers, Oceans, Mountains, Glaciers etc., - and my own body, its craft and different functions, I believe in the Almighty that is the source which I believe as God. Bible say you need 'Faith' because without 'faith' in you, you do not tend to believe in Bible. It is a call for survival, the basic natural instinct.

Evidence isn't proof. Evidence can be viewed in various ways which is why evolutionists and creationists disagree. We all look at the evidence in a subjective manner depending on our personal viewpoint.
Evidence on its own proves nothing it must be inserted into a model of some description; that is why faith is needed.

Because a dog doesn't know he's a dog, (Not that you are) but until someone tells them they'll never know what they really are. Yes the evidence is there for God but the faith (which is a gift) is like God tapping you on the shoulder and says: Its me. From that time on your faith keeps you connected to God because you now know what you are.

Since the Christians' flimsy arguments can be reasonably refuted, they have to rely on 'faith' since it can not be proven or disproven...
My 'faith' says all things that are beautiful b/c all the situations are right (IE-supermodels vs. deformed, retarded children) says nature gets it right sometimes, but doesn't other times.

I am glad you recognize God in Creation .....that is a step in the right direction....most atheists i know are in total denial.....at least you can see the Creator.
The next step is to put your faith in His Word and why He sent Jesus Christ to earth.....

The urethra running through the male prostate gland is enough to say you have to have "faith" we were, uhm, intelligently designed.
