I made no such assertion.
Why are you talking about the 10 Commandments?
The Ten Commandments were written by the hand of God on tablets of Stone (unless Moses and Jesus were both liars).
I suspect you may have never actually read the Ten Commandments, so I understand your ignorance. If you believe Moses or the Bible (or Christ's confirmation of the events) you will note that the following statement was written by the hand of God upon the Stone Tablets which Moses brought down from the mountain:
For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the LORD blessed the sabbath day, and hallowed it. (Exodus 20:11 KJV)
Do you happen to believe what God wrote with his own hand? Was God mistaken? Or was Moses a fraud? If Moses was a fraud, did he fool Jesus as well? Wouldn't that make Jesus a fool?
Since when does God speak of Himself in the third person? That passage sounds more like someone speaking for God.
You got me. It's been a while since I have read Exodus; usually when you see the Ten Commandments posted all that is written is the Commandments.
As for the rest of your questions, no I don't believe that God actually wrote them. I don't believe in the God of the Bible anymore. I'll back out of this theological discussion and stick with the science.
Hope that clears things up.
