Why Btonze Age?

[Rhondazvous]

We know that the different metal technologies didn’t hit everybody at the same time. While Israel’s “enemies” were well into their iron age. The desert tribes that later became Israel were not yet using iron, as seen in Judges 1:19,

Because of this disparity, Christian apologists feel they have a case against atheist who say that the writers of the Pentateuch were Bronze Age desert shepherds. They say the writers were of the Iron Age. To add to the confusion, scholars are now saying the books of Genesis and Exodus, were written after the Babylonian exile.

Questions:
1. What specific Bronze Age myths can be seen in the Old Testament?
2. Was Babylon heavily influenced by Bronze Age myths during the 6th century BCE, so when the Israelites were exiled there, that’s what they found?
3. What was Judaism based on before the Babylonian exile if there was no Pentateuch before then?
