Why not just lay it all out there?

You want the truth? You can't handle the truth.

No... really.

Time, to humans, is linear.
But, in reality it is a loop.
But that is a poor descriptor. We don't even have a concept to which to give a name, about what time really is.

Then we have the story of the burning bush.
And many people believe, it was a bush (woody short plant) that was on fire.
Not many consider that it was an angel.
And that this is what a person might see if they actually saw an angel instead of the projection of a person in white with wings.
If someone today had that experience, they might describe it like those mandelbrot pictures with the changing colors.

Further, how do you describe the universe to a group of beings who believe such weird things like "black holes", "dark energy" , "dark matter" & "gravity holds the galaxy together"? You can't just tell them, "everything you know is wrong", it's unhelpful. So, you try to steer them towards a point of insight
