Delusion.

Claiming a sense of Morality and Ethics, without God, is like spending money you don't have.  It is like having no Gold in your Knox: the money is printed, but it is worth nothing, based on nothing.  Morals without an absolute moral giver is a delusion.  It is something you want to be true, because you want it to be real, yet without being accountable to the one that makes all things real.
