Is it a false understanding or an incomplete understanding? Or, perhaps did we ask the wrong question?

Example. A generalize agreement over centuries and today is the sky is blue. But by todays knowledge we know that when transmitted light such as sunlight enters our atmosphere it collides with the oxygen and nitrogen atoms. The color with the shorter wavelength is scattered more by this collision. Because violet and blue are the shortest wavelengths the sky appears to be violet / blue. But because our eyes are more sensitive to blue light than they are violet light, we perceive the sky as blue.

So is the sky blue because it is blue or is it blue because human eyes perceive it is blue? Or is it blue because the neurochemistry of the brain is telling the eye what it is perceiving is the color blue? Or, have I now totally confused even myself?

If I imagine myself in that world, the common "knowledge", the perceived "truth" and accepted "facts" seem to make up the skeletal structure of that world. The "beliefs" of that world would be something I might imagine as soft tissue.

The way you state things there at the end bridges the gap for me - "believed to be true" makes perfect sense to me - though I don't know if I would spontaneously come to these words on my own, nor would I mind referring to those past false understandings as "truths".

I think the word "truth" is also murkier because it is used so much in a spiritual context. If religions are always seeking the "Truth", if people are always looking for their inner "truth" - it's already understood that this definition of truth has nothing to do with physical reality and facts. So in some ways, "truth" might even be its own antonym.
