Did on the second day, God said he created the sky or the firmament, which separated the waters above from the waters below. The waters below refer to the oceans and seas on the earth’s surface, while the waters above refer to the water vapor in the atmosphere. The firmament is described as a solid dome-like structure that separates the waters above from the waters below. This concept of the firmament was common in ancient Near Eastern cosmology, where the sky was believed to be a solid dome that held back the waters above.

I think the “firmament” is mentioned about 15 times in the King James Version of the Bible and refers to the expanse of the heavens above the earth. In the story of creation, as found in Genesis, God formed the firmament to divide the "waters above" the earth from the "waters below" the earth.

Chapter 6 of the Biblical Book of Jasher describes the events leading up to the flood and where the waters came from, including the instructions given to Noah by God to build an ark and gather two of every kind of animal, bird, and creeping thing 3. The flood began in the 600th year of Noah’s life and lasted for 40 days and 40 nights 3

Biblical Enoch described a place where there was nothing. Job describes the same: Job 26:7 He stretcheth out the north over the empty place, and hangeth the earth upon nothing. Enoch clearly describes the earth on a foundation (like so many other authors as seen above).

Which of the following models obeys Occam’s Razor the best?

Heliocentrism:

There are four vectors of contrary motion that The Earth and Sun experience as they fly though an expanding Universe, according to the wildly magical and imaginative Heliocentric Theory:

1. First, the Earth is allegedly spinning at approximately 1000 mph.

2. Second, while the Earth spins, it is also allegedly moving 67,000 mph around the Sun.

3. Third, while these two motions are occurring, the Sun is also allegedly, and in fact, our whole Solar System is allegedly orbiting around the center of The Milky Way Galaxy. We are supposedly moving at an average velocity of 828,000 km/hr.

4. Fourth, the entire Milky Way Galaxy is also allegedly going 670,000,000 mph on the membrane of an expanding Universe.

Enclosed Cosmology:

The luminaries are moving above you and you are standing on a flat, non-rotating plain with various Topographical features.

You decide.
