e.g. Gravity exists on Earth.
Truth the personal perspective of facts.
e.g. Michael Jordan jumps so high and for so long, it's as if gravity doesn't effect him the same way it does others.
Now consider what you don't understand.
Can you argue your facts or claim truth on the immeasurable, the incalculable and the supernatural where you can't or dare test?
We are humbled by our ignorance if we are wise...or insulted and indignant if all this time our facts and truth have been used to exalt ourselves.
