Therefore, "truth" can relate to an actual physical reality, or it can relate to the accurate recitation or describing of that physical reality.

In order to be clear in our discussion here, when we wish to refer to an actual physical reality (or to an semi-abstract description of a physical reality) we will use the word "fact".

We will use the word "truth" to describe the accurate recitation of the fact.

It is only possible to tell a "truth" when accurately describing "facts". If you are not accurate in your recitation of the facts, what you have said is "not true". It is, in other words, "false".

Here is where we immediately encounter a major problem. For example, is any "fact" that we observe actually real?

It is always possible that what we are observing is not real, but an illusion. Or, our observation might be incomplete, or limited. Or we might observe the fact, but infer something from it that is not quite accurate.
