How much can human beings handle all at once? Maybe it's part of a gradual revelation to get humans ready for more?
What if some kind of non-physical 'reality' is at work? It need not be what we see or imagine as aliens. It could be through ourselves.
Many humans sense a non-physical quality/aspect of themselves. How shocking might it be to realize how much more non-physical influence/ability is at work in all ways and all things? Perhaps we are plugged into the creation of all that we experience -- including all that we resist and blame on otherness. What is behind the physical reality that we're so sure of?
Well, probably, we would either dismiss that and blame it on a country and cause a war -- or we'd be driven mad by the sudden revelation of all we don't know. Christians would accelerate the Apocalypse... world leaders would claim to be representatives of superior alien races to lure more voters... people would be jumping off of overpasses, and there would be more mass shootings, etc.
Look at all the crap that people are already making up despite all to the contrary right in front of them. We are not ready... corn fields are all we can handle.
But... just as we can look into the night sky to see how much more there is than our little planet... we could also consider how much more there might be at work than physical reality. And that's what really interests me -- not the forms it takes. People argue over the forms... which could be anything... and that seems very shallow.
