In the sense of all of that, ID may not be "fact" but it is based on fact and is pretty solid, both on overwhelming evidence and on God's Word (Romans 1:20).
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.
