#1 - That's a fucking bowl, it's not flat; the Bible says God stretched a flat and level line across the Earth during its construction. -- Job 38:5
You're about as gravitationally compromised (dense) as they come. Did you ever see anyone stretch a measuring line across something? Look at the cross-country power lines. They sag, like a bowl. Your rendering of the Bible passage in Job doesn't have anything to do with flat. It has to do with God's ability, alone, to measure the earth, whatever its shape. Take a look at some of the Job versions of the passage you quote. No "flat" in them:
New International Version
Who marked off its dimensions? Surely you know! Who stretched a measuring line across it?
New Living Translation
Who determined its dimensions and stretched out the surveying line?
English Standard Version
Who determined its measurementssurely you know! Or who stretched the line upon it?
New American Standard Bible
Who set its measurements? Since you know. Or who stretched the line on it?
King James Bible
Who hath laid the measures thereof, if thou knowest? or who hath stretched the line upon it?
Holman Christian Standard Bible
Who fixed its dimensions? Certainly you know! Who stretched a measuring line across it?
International Standard Version
Who set its measurement? Am I to assume you know? Who stretched a boundary line over it?
NET Bible
Who set its measurements--if you know--or who stretched a measuring line across it?
New Heart English Bible
Who determined its measures, if you know? Or who stretched the line on it?
GOD'S WORD® Translation
Who determined its dimensions? Certainly, you know! Who stretched a measuring line over it?
JPS Tanakh 1917
Who determined the measures thereof, if thou knowest? Or who stretched the line upon it?
New American Standard 1977
Who set its measurements, since you know?
Or who stretched the line on it?

Show me where does it say the dome was polarized before the water was removed? Without the polarization there is no up and down and nothing to push on God's stretched out measuring line.
Show me where the measuring line was a bungie cord. You can stretch anything unless it is elastic.
The point? The meaning is that God does it in ways that people cannot fathom. It doesn't have anything to do with the shape.

Also how would you raise a dome without inflating it? My theory is God heated and softened the domes nickel-iron steel via magnetic induction and inflated the dome. When the magnetic flux was removed an electrically polarized reflective oxide layer was left on the interior of the domes hardened surface.
I'll have to give it some thought as to what God used as a measuring line, whatever it was clearly had "tension". Tension is also used as a term for voltage from polarized surfaces and the electric field is linear in nature. God would defiantly have the most technologically advanced surveying equipment in existence.
God uses things other than technology, even though He can use anything.

How could he use anything other than technology to engineer and build the Earth? Maybe you think God just made a giant wish and it came true?
You use all this wonderful ability to think, just to determine that the earth is flat, but you can't think about how God is way beyond technology?
Consider simple cause and effect. Science knows that cause and effect plays a role in everything that they have discovered. The also know that they have not factually found anything that does not operate through cause and effect... although they have their guesses about some things.
Knowing this, select an electron that was set in place in the beginning by God. God sent this electron out so that it reacts with other things in the universe... sorta like a pool shark hits that cue ball. That electron hits other material, and goes on to do whatever it is going to do next by bouncing off the other material, and making a change to the other material at the same time.
Now, consider that God did that with countless chunks of material all over the universe, and with the energy waves, as well. Some thousands of years later, all this bumping around is still producing life in abundance, people in abundance, intelligence in abundance, emotion in abundance, and all kinds of other things in abundance.
And you want to call this technology? Try throwing a handful of sand in the air and getting this kind of reactivity.
It's so far beyond technology that technology is like a microbe in the microscope. Technology is something that man invented to try to make sense of the things that God made without technology. God is allowing us to have some success, a tiny, little bit. We aren't capable of understanding what God did and does. The closest that we can come is to listen to what He is telling us.
The Job passage you mentioned says nothing about flat earth.
