You'll never get the truth about the work of God in this world if you follow the modern revisionist scholars, Mod.
And you'll never get to the truth about the work of man if you ignore them.
He planned to send a Savior from the tyranny of the demons starting all the way back in Eden.
He just kept it quiet.
In Jesus' time the demons were possessing many people who had either inherited or fallen into enough sin to allow them to possess them, and Jesus demonstrated His purpose and His power by setting them free.
Either way - Bible teachers do discuss the fact that the other gods might be treated as real as Yahweh in some parts of the Bible.
Your revisionist scholars have no clue about God's true plan either, and are continuing to seduce people away from His merciful salvation, joining with the demon gods themselves who are working tirelessly to keep as many as they can in their power and blind them to the promise of salvation.
Or maybe you've been seduced and the scholars are trying to explain the true nature of his merciful salvation.
That's kind of the problem with religion vs science. There's no way to tell the difference between these kinds of hypotheses.
