Hi tatteredsoul,

This is faulty logic based on association. Today, we tend to think of a day beginning when the sun rises and ending shortly after the sun sets and the moon appears to carry us through the night. However, neither of those heavenly bodies have even the smallest iota of bearing on what constitutes the definition of a day. They are merely events that we have come to 'associate' with a day. They do not have anything to do with what actually makes a day.
A day, you can look it up in any encyclopedia or google it, is defined as the length of time that it takes a planetary body to make one full rotation upon its axis. Therefore, if the earth was created spinning as it still does today, a day would pass in approximately 24 hours whether or not the sun, moon or stars even existed. God could have not even made the sun and we would still have days and years. A day being defined as the time of a single rotation and a year being defined as the time it takes for the earth to make a circuit of its orbit. The earth's orbit does not have to be around our sun, although current scientific models say that the earth's orbit is a function of the sun's gravitational pull.
Now, yes, we have come to understand that the gravitational force of the sun is what keeps the planets in their orbits, however, this understanding does have its own problem. If the gravitational force of the sun is what keeps the earth in its orbit, then why is the orbit elliptical?
We know that gravitational force becomes stronger the closer you get to the object producing it. We have proven this through the space program. It takes an enormous amount of thrust to move an object like a space flight craft off of the landing pad, but as the craft moves further away from the gravitational pull of the earth, less thrust is needed until it is completely outside of the earth's gravitational pull and then it will move about with just small directional thrusters.
We can orbit the earth, but if we are still within the area of its gravitational influence, the craft will eventually crash to the ground because it begins to be slowly pulled back to the earth and then as it gets nearer and nearer the descent speeds up. It is actually a very exacting calculation as to where satellites need to be to maintain an orbit and there have been several cases of satellites falling through the earth's atmosphere to the ground although the heat generated by this process pretty much destroys them before they get here.
So, why, when the earth is closer to the sun in its orbit doesn't it pull more towards the sun? We have devised a theory called the theory of angular momentum which does a reasonably good job of explaining this phenomenon, but unfortunately falls a bit short. There are some who say that it's because the earth revolves faster when it is near the sun. Ok, then why does my clock still mark the days as 24 hours whether the earth is spinning fast or slow? This is not to be confused with the actual daylight hours decreasing, but the actual length of a day. If the earth is spinning faster for a couple of months, then why doesn't my clock say its midnight when the sun is coming up?
So, there are problems to be worked out yet as to why the earth continues to revolve around the sun at varying distances from the sun and still retain what appears to us to be a fairly stable orbit for decades, centuries and such. Even Newton, who did so much study involving gravity, questioned this ability based on the design of the earth's orbit.
The answer, of course, for the believer is that God holds the universe in its place and the stars and planets in their courses. It is merely by the power and design of God's creation that the universe will exist for all eternity. We are told that there is coming a time when the sun and stars will flee from the heavens. That in the eternal existence there will be no need of the sun to give light upon the earth for God will be our light. Does this mean that the earth will just travel for eternity with no orbit, but merely wander throughout the universe? Possibly. After all, so long as the atmosphere remains covering the earth people can still live on it no matter where it is in the universe.
However, these thoughts and questions are not the subject of this thread. I merely point out that the sun and moon are not necessary for a day to pass on the earth. Their appearing and setting are merely events associated with a day.
God bless you.
In Christ, Ted
