This is true. In the end, none of us truly understand anything well enough to speak like it is absolute, especially things like theories.
You know, if we wanna go into this crap about the physical versus the unseen, you might as well bring in all the hypocriticalityof the science community to light. I think of examples like a black hole, dark matter, dark energy, quantum foam (that's a really good example) etc etc. From what I can tell, the word "scientific fact" doesn't actually exist. There are many things that we take faith upon, particularly, scientific communities put faith in Isaac Newton (who btw trusted deeply in the Bible) along with many other significant scientists, I don't see why suggesting Biblical recordings as reliable is off either. I'd rather place my trust in the most significant piece of literature that was written over a period of 1500 years by 40 different authors w/ 66 different books, in three different languages on 3 different continents all in harmony with one another (if read in it's proper context) and has remained the most valuable book in all of history, over the assumptions of one Charles Darwin, a man who after losing his 10-year old daughter, had to find a way to explain her death and feel peace about it.

and his doubts..

And so we all know the differences, lol:
oFact: In science, an observation that has been repeatedly confirmed and for all practical purposes is accepted as "true." Truth in science, however, is never final and what is accepted as a fact today may be modified or even discarded tomorrow.
oHypothesis: A tentative statement about the natural world leading to deductions that can be tested. If the deductions are verified, the hypothesis is provisionally corroborated. If the deductions are incorrect, the original hypothesis is proved false and must be abandoned or modified. Hypotheses can be used to build more complex inferences and explanations.
oLaw: A descriptive generalization about how some aspect of the natural world behaves under stated circumstances. (This is where gravity fits)
oTheory: In science, a well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses.
Also, EasyE, that was a tasteful comment worthy of note. But lets not go any further. Someone else can have the last word but I will also opt out of pursuing this any further.
