Scientists certainly do not shy away from the word "fact"; they use it all the time to refer to... well, to refer to facts. Most scientists would not call a theory a fact; why would they. Similarly most scientists would not call a "fact" a "theory".
This notion of your is basically ridiculous and absurd. As is your assertions that "However truth, which is from the Bible, God's Word, never changes." That's laughably false.
Truth does not need the Bible; Truth pre-existed the Bible and Truth will still be Truth long after the last Bible has crumbled onto dust and even mankind perhaps passed from the scene. Truth is innate in existence. It's the job of science to define and help us understand the truths innate in reality.

Science does not define truths. It defines THEORIES. Math does the same, so does law. Law takes the best evidence and goes with it. Nothing is 100% certain. But God's Word, the Bible is certain.

We've gone full circle. "Existence" is creation by a Creator proved by evidence beyond a reasonable doubt of ID. So before anything was the Creator God. "In the beginning God created the heavens and the earth" (Genesis 1:1). So God was before creation. His Son, Jesus IS TRUTH (John 14:6) and his word, the Bible is truth (John 17:17). Truth never changes, it is an absolute. Science, math, law, life, facts, and theories change all the time. God exists as evidenced by ID and He is the one constant to hold onto because everything else is subject to change.
I would love to know how many people on this thread love to pretend they take the Bible literally, and then claim alcohol is an abomination. If they are naive enough to be that hypocritical and self-deceitful, no amount of talking to them can ever bring them around.
