It's funny to see Biblical theists arguing for "rational, logical, and consistent reasons for morality", since they certainly have no basis for any such thing.
For example, killing babies is sometimes the right thing to do according to the Bible:
'Now go and strike Amalek and utterly destroy all that he has, and do not spare him; but put to death both man and woman, child and infant, ox and sheep, camel and donkey.--1 Samuel 15:3
Many other Biblical examples could be given, demonstrating theistic justification for almost every conceivable act of immorality. For instance, Judges 21:10-24 authorizes rape.
In light of these sort of Biblical commandments, the argument put forth in this thread is quite silly.
Sure we do...God is the author of our rationality, whereas the author of the Evos logic is random processes plus differential survival.
