If the given conditions of this excersize is 'rational or irrational' as these are stipulated for the excersize, then the argument is easy. Perhaps the exersize is to show the difficulty of distiguidhing between the two. Of course the anthropologists have limited the discussion to behavior.
I suppose rational has a limited definition and so the argument would evolve to definitive ends of : no god. Rationality automatically excludes and negates an absolute god. The arguments behind that are empty and (ironically) self indulgent.
I wonder what the purpose if the debate is.
How shrewd the professor is would be a more interesting discussion. Maybe gear your argument in that direction.

Re: [HELP] Irrational to believe God exists without evidence
God is an irrational concept. To make an argument as to why a god is not a rational posit is in itself an irrational exercise. That is, unless one reduces it to behavior of those who assert it.
