The picture above is a good example of personal interpretation.
Looking at this verse in Greek (not in the KJV) it says...
Ὦ Τιμόθεε τὴν παρακαταθήκην φύλαξον ἐκτρεπόμενος τὰς βεβήλους κενοφωνίας καὶ ἀντιθέσεις τῆς ψευδωνύμου γνώσεως
The word used was γνώσεως (gnōseōs) not ἐπιστήμη (epistemē). Episteme is what Ancient Greek use for science which was derived from the word ἐπίσταμαι, "to know". Now, the word science here came from the word Latin (scientia = knowledge), thanks to the Vulgate, but that is not the science as we know since science doesn't mean knowledge (in the Greek sense) but "the pursuit of knowledge."
So does 1 Timothy 6:20 means "science" or "evolution?" If you will know your Bible history correctly, the First Epistle to Timothy was written in CE 62-66. That was the same time a lot of Gnostics gospels were already circulating and the Pauline Christianity was trying to preserve itself against church heresies. So knowledge here means "false teachings" from gnostics "false doctrines" about Christianity, not about "Theory of Evolution" or from science which is about the pursuit of knowledge.
