Anyone proposing Flat Earth while using this for their Old Testament:
Is the Septuagint the same as the Tanakh?
The Septuagint does not consist of a single, unified corpus. Rather, it is a collection of ancient translations of the Tanakh, along with other Jewish texts that are now commonly referred to as apocrypha.
What does apocrypha mean?
apocrypha, (from Greek apokryptein, “to hide away”), in biblical literature, works outside an accepted canon of scripture. The history of the term's usage indicates that it referred to a body of esoteric writings that were at first prized, later tolerated, and finally excluded.
What is Esoteric Writings?
a personal interpretation!
...is definitely following GREEK MYTH, who proposed Flat Earth Idealism!
