The chronology of the Hebrew scriptures is an elaborate system of lifespans, "generations," and other means by which the passage of events is measured, beginning with Creation and extending through other significant events. The timespan of the Hebrew scriptures is almost 4000 years of history. beginning with Creation and ending around 164 BCE with the last Prophet.

In that 4000 years, no one has ever seen a devil, ever seen a demon, seen a demon cast out(exorcism), never seen a demon-possession(body snatching).

Jews don't worry about such thing, or fallen angles having sex with women as christians believe , this does not happen. Noah never had a problem with them. Abraham, Issac, Jacob, Moses, Aaron, David, Solomon, Isaiah, Jeremiah, etc never encountered demons and devils! Nor or they ever mentioned by anyone in the Tanakh.

Then the greek NT comes along centuries after the last Hebrew verse. The timespan of the NT is less than 100 years. In the NT, demons are seen about 100 times. All of a sudden in that 100 years, there are demon-possession(body snatching), demons cast out(exorcisms). None of which ever happened in the history of the Jews.

Jesus has a conversation with demons!! That should be a hint about jesus being a fictional character. Jesus and the disciples seem to run into them around every corner!!

There are many many reason why the greek new testament is fiction, jesus/yeshua/yahusha/yahushua talking to demons is just one of them!
