"the evidence shows the Israelites being mostly of canaanite orgins" - don't get too hung up on this because they have indeed shared the same lands for 1000's of years so no problem
"king David and Solomon most likey did not exsist" this doesn't mean anything - in 100 years ppl might say you didn't exist but it is a pointless statement supported by nothingness
"the bible is full of stories taken from even older writings" - the easy answer is for me to say its the other way around my friend. Again pointless statement that you cannot substantiate and i cannot be bothered to substantiate. Why don't you try and answer my paper on egyptian history?
You mention babel so i will conclude by mentioning Excavations in and around the ruins of ancient Babylon have revealed the sites of several ziggurats, or pyramid like, staged temple-towers including the ruind temple of Etemenanki. One fragment found states “The building of this temple offended the gods. In a night they threw down what had been built/ They scattered them abroad, and made strange their speech. The progress they impeded |Bible and Spade, 1938, S. L. Caiger, page 29|
No need to fear persecution from bible groups with that one because it supports the bible... now why don't they teach that in schools today?
