In this article, we will deal with the claims of a flat-earth advocate named Jeff. Jeff is a friend of a friend of mine, who objected to some of the proofs I gave that demonstrate the earth is spherical. Since Jeff’s claims have been refuted elsewhere, I agreed to answer them but only if I could post them publicly on this website so that others may benefit. Jeff graciously agreed.

Previously, we examined some unusual claims made by Troy, who asserted that the days before the global flood were four to six hours shorter than days today. We found that Troy gave no biblical or quantitative scientific evidence to support his claim….
Today we will examine Troy’s claims that asteroid impacts and/or lunar recession have reduced earth’s rotation period by 4-6 hours per day since creation.

We here examine some assertions made by Troy, a young earth creationist who has made some very unorthodox claims about conditions before the Genesis flood. He believes that the length of a day was much shorter before the flood, only 18 to 20 hours per day, and that the flood somehow changed this. As errors go, this is a fairly mild one, and there is nothing heretical or theologically damaging about such a speculation. But the way in which Troy attempted to defend his conjectures involved serious errors in reasoning, in science, and in biblical interpretation.

We previously explored the differences between the inverted retina of the human eye, and the verted retina of cephalopods. We found that each system was well-designed for the typical environment in which the creature lives. This prompt us to ask what other types of eyes the Lord has created. From a biblical creation perspective, we expect to find both similarities (due to having a common Creator who is a God of order) and differences (due to the Lord’s creativity) in the eyes of different varieties of animals. Furthermore, we would expect each type of eye to be well-suited for the organism in its environment, and irreducibly complex. And this is indeed exactly what we find.

Having examined some of the remarkable design features of the human eye, we here look at a feature that is sometimes claimed to support evolution: the inverted retina. Evolutionists claim this is a backward system that resulted from chance mutations. Far from being evidence of evolution, the inverted retina is extremely well planned. Furthermore, not all creatures have an inverted retina. Rather, each creature has a vision system that is well-designed for its environment.

The human eye is a marvel of design. All the parts work together to provide us with a vivid and colorful mental picture of our surroundings. As an astronomer, one aspect of human vision that I find particularly amazing and useful is the ability of the eye to adapt to extremely different lighting conditions. At night, the eye adjusts to be able to see stars that are 12 trillion times fainter than the sun. The way this mechanism works is ingenious and is merely one example of the cleverness of the Lord and of His grace toward us.
