The Bible mentions that angels took a man named Enoch outside of our "half-dome" system. However, the book that detailed his experiences was later removed from the Bible.

Enoch described what he saw beyond the dome in vivid detail, likening it to a half-dome snow globe resting on a table.

That is why they hate the flat earth theory so much because it's true and the evidence is also in the bible. They really hate the creator and want to hide the truth from us all.
