Thank you for pointing this out. It's rather frustrating to hear the morality argument trotted out when animal species demonstrate a moral sense, and social animals like chimps are close to our own moral compass. Sure, the animals don't get to wrangle over it in debates, or write treatises about it because they don't have our specialized skill of language, but they have instincts that give them a remarkable sense of fair play.
In truth, if I were God and designing creatures, I wouldn't make just onc species a recipient of a moral code, I would put instinctive instructions at the basic programming of every species that achieves multi-cellular level. The transistion from unicellular to multi-cellular may be the very beginnings to moral instructions in the genetic code, as what had been previously single cells operating independently pooled together and achieved a fairer division of the available resources.
But I'm starting to drift from the topic, just suffice it to say I don't find the morality argument in any way convincing that there is a god.
