The requirements of God in theism are extremely substantial and demanding. For example, the Wikipedia article on the attributes of God in Christianity lists twenty-eight attributes (see Appendix 2), including omnipotence and omniscience. These attributes have been the subject of theological and philosophical debate over millennia. Many religions also demand features such as heaven, souls and miracles. In attempting to associate these attributes and features to a naturally emerging God, appeal could again be made to the idea that predicting the scientific knowledge of the future is not possible. Thus, in the future it might be possible to obtain scientific evidence for these attributes. For example, perhaps our stream of consciousness with associated memories could be preserved disembodied in a way that we now cannot imagine through current science. One version of the Kardashev scale involves an extension of the ability to control smaller and smaller entities down to elementary particles, and then to create organized complexity from them (\citealt{Barrow_1998}). Exploitation of this knowledge could render naturally what are called miracles, through transformation or creation of matter.
Many ontological proofs of the existence of God, consider God to be a supremely or maximally great or perfect being (see for example, \citealt{Oppy_2018b}). For example, the proof of St Anselm considers God as a being “than which nothing greater can be thought”, where greatness can be in qualities such as omnipotence and omniscience. Assuming both the unlimited possibilities for evolution in a potentially infinite number of universes and the plenitude principle, then maximal greatness on a scale such as the Karadashev scale ought perhaps to be achievable. The maximum may be set by the physical properties and laws of the universes involved. Unlimited possibilities may however imply not only an unlimited number of maximally great entities but also a multitude of minor gods at various stages of advancement. This 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 constrained by whatever physical laws could be operational within the multiverse in relation to interaction between universes and the gods they contain.
