Isaac Newton thought he could turn lead into gold.
Yes, he did. Newton was one of those insane geniuses you hear about, like Vincent van Gogh. In fact, the two were very similar. They did not get along with other people. Both were known to become extremely angry when challenged. This does not, however, change the fact that they were geniuses with good ideas. That is true
Argumentum ad hominem.One model should be enough. Imagine this above us.
Look closely at the Earth in this image. It is distinctly round. This model works based on a spherical Earth. If you flattened out the Earth, this model would no longer explain the view of Mars in the sky. Look at
http://www.jimloy.com/cindy/ptolemy.htm. First diagram shows a red arrow. This is an observer on Earth observing Mars. The planets both move, but the arrow itself slows down, goes backwards, slows, and turns forward again. This is what causes the view to be like the second diagram. Ptolomy believed that the Earth was a sphere in the center of the universe, so his epicycles were his explanation for the behavior. It makes no sense on a flat Earth.
FET only has 5 planets.
Another mind-bendingly obvious FET-is-wrong. Amateur astronomers see them Uranus and Neptune every day.

A logical answer is, "How do you know those are actually them?" Because they pointed their telescopes at a specific angle to find the planets based on the known RET-based orbits of the planets. Click on the first link again if skeptic.

Just to clear things up, these are the days of the week:
http://deoxy.org/time/d2k/thedays.htmThere were five planets, a sun, and a moon visible to the ancients in the night sky. This is probably what the seven days in the Bible came from in the first place (just a wild guess).
All in all, the week was based off the celestial bodies, not the other way around, exemplified well by zarg.
