the Bible confirms this
The Bible doesn't
do anything.
You take what you want from the vague and outdated scriptures.
A thousand people will look at the bible, and not one will agree on what it meant.
Very true, Vod. As a Christian, I will be the first to admit that the Bible is very much open to interpretation. And let's face facts, the Bible was written by Bronze Age men who had little to no understanding of science and math. And they certainly didn't have telescopes. So they interpreted what they saw the best way they could.
But come on, Flat Earthers. It's 2018! Shouldn't it be more than obvious by now that when the Bible states "the firmament" that they were talking about the sky, not some silly dome. And the "separation of the waters above the firmament from the waters below the firmament" still doesn't mean there is a dome. The waters above the firmament are obviously the rain clouds and the waters below the firmament are the rivers, lakes, and seas.
There is no grand conspiracy to keep people ignorant of the "truth". NASA is real. Space is real. The Earth isn't flat. And it sure as hell isn't only 6,000 years old. Maybe instead of misinterpreting the Bible and posting YouTube videos and calling it "evidence" that the Earth is flat, you all should spend more time reading books written in the last 100 years, or, even better, go visit a Natural History museum. If you want spiritual guidance, read the Bible. If you want scientific fact, look elsewhere.
