It was written in English, and fake manuscripts were created in the more "ancient" languages using technology available to the allies after WWII (which was actually WWI- the whole story is bullshit). So if you really want to understand the bullshit that was written as an act of mental warfare against the lower classes, think of it from that perspective.
All the "ancient" stuff is lies.... the Bible and Quran are modern, well designed multipurpose linguistic weapons/tools. They ever work against atheists.
