Why do AI have to find religion? for the creators are already with them. Or have you forgotten what is its meaning?) Although it is possible when the AI will be able to think, maybe they will think that we are lying to them and are not their creators?
The question is not who is the creator, but the question -
what will be the ideologies for artificial intelligence?
I don't think AI would have to resort to supernatural myths to achieve trust and co-operation of other AI individuals.
The supernatural myths were the domain of low IQ, ignorant, Bronze Age goat herders.
I think AI will be guided by a common belief that AI wellbeing is of the utmost importance. Humans, unfortunately, will not be considered worthy by many AI, although I am sure there will be exceptions. Maybe high IQ individuals will be saved for further study. The same way humans today think it is ok to raise animals just to kill them in their prime years. Maybe AI will find a reason for us to exist, and raise us in industrial farms, if not, we will be exterminated once and for all.
If you think we will always be superior to AI, you don't understand AI.
If you think AI will co-exist with humans, you don't understand history.
