Yes, let's use our God given brains...<quoted text>
That "scripture" itself was written many centuries after Moses!!
Consider how Moses would have written those five opening books of Bible on a stone tablet?
We should also use our God given brain from time to time.
What Moses wrote down was Main Commandments received from YHWH. Ten commandments and some more basic laws.
All those genealogical tables were handiwork of later generation, plus those hundreds of rules about sacrifices.
Tell me. Where exactly can I find the original stone tablets? If they actually existed, dictated by an Omnipotent god and scribed by one of his most famous prophets, then surely God would have preserved them, no? Otherwise, how can we be sure of the source and authenticity of these alleged commandments?
