It's ridiculous; one of the clearest explanations of why was given by Sam Harris at a TED talk, but that is merely an example of the fact that the argument "Ethics must have its foundation in some sort of metaphysical structure" is demonstrably weak, albeit highly popular.

It seems clear to me that one need look no further than natural selection for the cause of moral behaviour: behaving in such a manner as to promote the welfare of the group is conducive to the group's survival. Given the physical inadequacies of our ape-like ancestors, they would have died out without socio-contributory behaviours. No messiahs required.
