And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so. And God called the firmament Heaven. And the evening and the morning were the second day. (Gen 1:6-8) On day one there was only one body of water, and that was on the earth, which God separated, the water above from the body of the water below. So what is this firmament that God made here between the waters? Verse 20 speaks of …fowl that may fly above the earth in the open firmament of heaven. (Gen 1:20) We know that birds do not fly in outer space because they need the atmospheric heaven or firmament to live in, neither do they fly in the dry land. So as some Flat Earthers claim, the firmament is not a pounded out metal type dome fixture that has stars attached to it over a flat earth. Notice also that God called the firmament that He created on the second day “heaven” and not “the heaven”, these are not interchangeable in the creation account, they are not the same thing – one was created on the first day, the other on the second day. The Heaven that God created on the first day is where He placed the lights on the forth day: And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years: And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so. And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also. (Gen 1:14-16) So the lights that God created on the forth day, are not in the “firmament heaven” between the waters that He created on the second day where the birds fly, but they are in “the heaven” that he created on the first day. And many Flat Earthers digress to proclaim that the moon is luminous in itself and does not reflect the suns light as if reflected light from the moon would not qualify as the “lesser light” to rule the night, this specious claim only tends to discredit their major thesis. Mere observation of the phases of the moon in conjunction with the position of the sun verifies that the sun is shining upon a spherical moon. ... https://www.youtube.com/watch?v=iLUTup05t7Q
