Fourth, if the Bible is proven to be contrary to fact, and there is no God, then it would be totally irrational to believe in God. If that is the case then we should all become atheists. That also means we should do whatever we want to do. There would be no universal moral law in the universe. Whatever benefits us or pleases us most in this life, we should pursue. It means the only right and wrong that exists is dictated by society. The only penalty for crossing these boundaries is punishment by society. These defintions of right and wrong could vary greatly from society to society. There is no reason that society cannot decide that anything is right (regardless of our present moral understandings) based upon the desires of society. This can include killing infants, the elderly, the handicapped, etc. because they are not productive or wanted. This can include exploiting those who are weaker. The playing field is wide open. It is not unimaginably idiotic. I can sure imagine it, and it does not look very good.
You assume that all morality comes from the Judeo-Christian scripture?
There was morality long before the scripture was written. As for the end of the above statement, There are societies that do just what you say in one form or another. Try white supremacists, Neo-Nazis & the KKK, all three are Christian.
