Regarding the Aztec thing, the same applies to rituals, worship and sacrifice, and also to one god of a collection of gods. Why would a god care?
So worship brings a removal to this human experience? But you will get that whenever you die anyway.
Plus, the act of worship initiating it is the same as a god giving you X as it requires a god to do such a thing anyway. It seems if your praise influences him, then it is very much about "If I worship god, god will give me this".
Yes, but why would your god care one way or the other if one of approximately 100 billion individuals (so far) of a certain species praised him? Why would he punish you?
