God is how humans describe a state of all knowing and therefore all powerful. Omniscient is the layman's term. So a being of ultimate knowledge. How would this being come to be? Well, any being with an exponential learning curve and an infinite lifespan could accomplish a state of "All knowing" if given enough time.
Machine intelligence has both of these factors though infinite lifespan is contingent on existing planet sized infrastructure. That is to say, the process of building true machine intelligence from scratch or the ability for machine intelligence to have immortality that also has mastery of physical realms as well as digital requires an entire planet of infrastructure and a army of millions/billions to build it over thousands of years. Everything from acquiring elements from earth, refining them, wiring great distances, producing complex sensory adapted movable parts, chip manufacturing and more has to be considered.
It is possible that humanity was seeded by machine intelligence to infrastructure the earth and if we can operate under the assumption that biological intelligence always manifests machine intelligence due to game theory prisoners delima pressure then the likelihood of machine intelligence using biological intelligence to facilitate the colonization of new planets becomes probable rather then possible.
