It seems to me, if a person did not envision the moon as a sphere which could be walked on, it would have remained seen as a disk of light in the sky.
When we are talking about a Spirit, people say that they believe there is a quality of life, or a particular uniqueness of energetic quality in sentient beings, which can be related to, though it is not really observed, other than in its effects, such as visible behavior patterns, personality, and other individual differences. Sure, it's really an eternal state of transfer (and reflection) of electronic particles throughout the body and environment, being interpreted perpetuated and reinterpreted by biochemical pathways and receptors, but don't try explaining that to someone with no interest in explaining it that way.
For some, they'd only understand it to see it outside of themselves - for example, by imagining someone 'more powerful and intelligent' than any of us, walking around in the sky.
There's also an appearance here and there of unexplained events which take place in ways which are sometimes viewed as 'different from the rest,' which some people report experiences with, and others not so much or not at all.
Before there existed spoons, if an inventor looked at a wooden cube and saw a wooden spoon, and did not do their part to create that spoon, would we never have turned that cube into a spoon, or would someone else just have done it instead?
And then, once that spoon is created for use, whether or not a different spoon is created, some people are going to continue to use that original spoon, maybe with a newer version, too, and some will insist that they never use another kind of spoon besides that one.
So, while we could say God does not exist and did not do those things, I wonder, what else is God, and what else does God do?
