Why are other civilizations ignored in the Bible?

[Minimalist]

Mark is also an entirely Jewish story. No mention of Jesus coming to save everyone (in fact the opposite - just the Jews). Its only in the bolted on bits after Verse 8 in the last chapter that we get the "spread the word" message.

Those scholars that our new-found troll seems to be so fond of, do not agree.

Most modern scholars reject the tradition which ascribes it to Mark the Evangelist, the companion of Peter, and regard it as the work of an unknown author working with various sources including collections of miracle stories, controversy stories, parables, and a passion narrative.

The author wrote in Greek for a gentile audience (that they were gentiles is shown by the author's need to explain Jewish traditions and translate Aramaic terms) of Greek-speaking Christians, probably in Rome (Mark uses a number of Latin terms), although Galilee, Antioch (third-largest city on the Roman Empire, located in northern Syria), and southern Syria have all been offered as alternatives.[8] He may have been influenced by Greco-Roman biographies and rhetorical forms, popular novels and romances, and the Homeric epics; nevertheless, he mentions almost no public figures, makes no allusions to Greek or Roman literature, and takes all his references from the Jewish scriptures, mostly in their Greek versions.[9] Adela Yarbro Collins, Buckingham Professor of New Testament Criticism and Interpretation at Yale Divinity School, has argued that the author intended to write history, but not in the modern sense, or even in the sense of classical Greek and Roman historians, but "history in an eschatological or apocalyptic sense," depicting Jesus caught up in events at the end of time
