Interesting. Are you aware that what is believed to be the royal library at Ebla in Syria was discovered in the 1970s. They excavated over 2,000 clay tablets. predating the Bible by about 1500 years.

The tablets contain the names of all of the Prophets mentioned in the Old Testament with the exception of Moses. The theory is that they were the Hebrew's pantheon of Gods from the time when they were polytheists but being so imbedded in the popular culture the later priestly caste were unable to eradicate them so effectively downgraded them from gods to prophets.

Also, the original meaning of Cohen is soothsayer, not priest.
