We truly are trying to understand your position and knowledge.
That's a little difficult to believe. I say the same thing over and over and it gets twisted.
"There's really not such a thing as "true" and if there were it would be based on experiment not facts and evidence and most assuredly not by logic."
"Truth" is a statement concerning reality that is universally correct. It is impossible to make any such statement in modern languages because word meaning is ephemeral. It is also highly improbable due to the complexity of reality and because there are an infinite number of perspectives.
"Experiment" underlies all modern science BECAUSE it is the only means we have to glimpse reality. Every experiment shows a sliver of reality.
"Facts and evidence" is everything that supports our beliefs. We can't see evidence that doesn't support our opinions.
"Logic" can not exist in confused language. Inductive logic is a mess because it's based on taxonomies which are mere mnemonics. Deductive logic is a little better but words still can't correspond directly to reality in confused language.
You can't mix and match these words because they are intended more like a dictionary and scrambled dictionaries are useless.
The only thing we have are experiment and reason and we must use a language confused at the tower of babel to communicate about experiment and reason.
