A distinction can be drawn between the emergence of an advanced entity on a Kardashev scale capable of creating universes and a maximally great entity which is God. For example, advanced extraterrestrial, as in the zoo and planetarium hypotheses, may deceive us, though Webb (2015) doubts this, but they would not have the maximal greatness of God. The focus here is that the naturally emerging God tends towards the entity of maximal greatness rather than be a highly advanced entity from our own or other university that we may be deceived into believing is God.
 Maximal greatness may be set by the physical properties and laws of the universes involved. Unlimited possibilities may however imply a multitude of gods at various stages of advancement, which could be in line with religions which have many gods. Perhaps one way to generate a single God of maximal greatness would be to imagine a process of merging within this multitude of gods. Another way might involve competition and natural selection between gods. Another way might involve collaboration and agreement between gods. Such processes would need to be constrained by whatever physical laws could be operational within the multiverse in relation to the feasibility of interaction between universes and between the gods they contain.
