Primary it is a attack on the legitimacy of the Bible. The Bible was translated to the common tongue during the reformation, and finished in 1611, by the committee put together by King James. Part of the counter reformation was establishing the heliocentric model, so people would not take the Bible serious, even as they now have access to it with their thumbs on their smartphones.

The Bible is clear, earth is fixed and stationary. If people think we live on a spinning ball flying through space, then they think the Bible got something wrong, and the Bible no longer is holy (whole): people in the past must have been primitive and uncivilised, not reliable when they witness what God has told mankind, and the coming judgment that we will face; is things you might hear from modern day atheists, doing their best to destroy the faith of the Bible being the perfect preserved word of God, made available to all generations.

Satan is placed in charge of the world, he is the king over the children of disobedience. Satans job is to cast doubt over what the word of God says, so that is what he does. Maybe Satan thinks that through sheer number of lost souls filling up the bowls of hell, he will be saved: God reproves him on this though, in his perfectly preserved word, being the same today as it was 2000 years ago.
