One, what does it matter whether I have children or not. The notion that everyone is sinful by nature is preposterous.
No it isn't
Secondly, you might try and actually READ my post. I said that the law of gravity or any other physical laws for that matter are man made. Do you even know what a physical law is?

However God's law is not man made.
