And I'm only stating what Jesus said (funny how he seems to be in agreement with Torah!):
Matt 5:18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
Mat 5:19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach [them], the same shall be called great in the kingdom of heaven.
Mat 5:20 For I say unto you, That except your righteousness shall exceed [the righteousness] of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven.
Chew on that 5:20 for a while.
As to the rest of your post...Do you believe that God took the guise of a burning bush and taught Moses a few tricks?
Do you believe God makes mistakes? [Gen 6:6] Why did Adam live to be 900 when God said that he will surely die on the day when (not if) he eats the forbidden fruit? [Gen 2:17]
