When we consider the similarities between the third day and the Millennial Kingdom we should realize that, if flat Earth is Biblical, then maps of the supposed flat Earth should have Jerusalem at the center. They don't.
The Whole Earth
Earthquakes and Meteorites
Zechariah prophesies an earthquake which is equal in severity to one that occurred in the time of Uzziah, King of Judah. The historical earthquake that this refers to was prophesied by Amos.
Ezekiel’s Hydrology
The Millennial Kingdom hydrological cycle is a reestablishment of the original condition of the earth, when Eden was at plateau at the top of a mountain that filled the whole Earth.
The Mount of Olives
The Mount of Olives will split into a northern and a southern half creating a great valley. This will is to allow water to up well from within the Earth, flowing out to the east and west from the temple in Jerusalem.
The New Deep
Ezekiel tells us that a great river will issue forth from the temple in the Jerusalem. This is part of a hydrological cycle which doesn't presently exist. It's established along with the Millennial Kingdom.
A fixed or established place: מָכוֹן – makon
The universe has an absolute frame of reference: the Earth is at the center. This is why the observable universe is a sphere of cosmological bodies which has an even distribution in every direction that we look.
Hezekiah Superstar
The sign of the sundial was a precursor to the main event: during the the night 185,000 soldiers of the Assyrian army became dead corpses. The Assyrian king fled to Damascus where he was killed by his own children.
The Life of Isaiah
The information that we have suggests that Isaiah was an old man at the time of his death. He saw Jerusalem dwindle in prosperity and fall from powerful to vulnerable.
Two Years Before the Earthquake
Amos prophesied the coming judgment of God two years before an earthquake. How did he know that it was coming? Amos was a herdsman and probably spent his nights outside. Did Amos see something in the heavens?
Dinosaurs in Jerusalem
We are told repeatedly by Jeremiah that dragons only inhabit places where there are no humans, or from where the humans have already been driven out. Judah only became a den of dragons after it became desolate.
