Satellite technology is really quite easy to understand on a flat earth. Lets first look at the Dome. The King James Bible explains it...
Gonna have to stop you right there, fella.
How many times, the Bible is not a science book.
Look at Job 38:
4 Where were you when I laid the foundation of the earth?
Tell me, if you have understanding.
5 Who determined its measurements—surely you know!
Or who stretched the line upon it?
6 On what were its bases sunk,
or who laid its cornerstone,
7 when the morning stars sang together
and all the sons of God shouted for joy?
8 “Or who shut in the sea with doors
when it burst out from the womb,
9 when I made clouds its garment
and thick darkness its swaddling band,
10 and prescribed limits for it
and set bars and doors,
11 and said, ‘Thus far shall you come, and no farther,
and here shall your proud waves be stayed’?"
God is putting Job in his place but not in a way which is meant to make any sense scientifically. The language is clearly poetic.
I think Satan has better things to do than try and convince people that the earth is round when it's really flat.
I always think it odd that some Christians, when presented with scientific ideas which challenge their understanding of Scripture, immediately conclude that the science is wrong and don't consider that their understanding of Scripture must be wrong. Even the church apologised to Galileo in the end and admitted they were wrong.
