Morality Must Come from a Higher Source

For a moral code to be effective, the code must be attributed to, and vested in, a non-human source.  It must be beyond the power of humanity to change it to suit itself.  If that non-human source can be shown to be false, then the moral code that it endorses cannot be absolute.  It will become a matter of choice, or have to be kept in place by the threat of force, or a mixture of both, like any other code of human invention.
