That sounds like a very vague criteria. I don't think that 'conciousness' has been defined very well. Nor, do I think that the link between 'conciousness' and 'morality' has been made except in a metaphysical sort of way.
If non-human species can be demonstrated to act morally, how does that affect the 'moral arguement for god'. If a non-human species can not be determined to act morally, how does that affect that arguement?
If a naturalistic method can be shown to be able to produce morality, how would that be evidence for a god one way or another?
It looks to me like the whole arguement is taking a bunch of what ifs,
then saying 'Those assumptions demonstrate god'. There are too many assumptions that are unprovable to have that as a valid arguement, IMO. I don't see how you can demonstrate that there IS an objective morality. Before you can have morality be an arguement for a deity, you ahve to first demonstrate that objective morality exists, then you have to provide a way to show that the specific morality is object, but it could not have developed naturally.
