It has nothing to do with smugness. We are unable to present our reasons for accepting evolution because the Christians who show up here to argue the point don't know a damned thing about the subject. Not one damned thing. Your misunderstanding of what a theory is demonstrates to me that you are just another one in the long line of VOLUNTARILY ignorant Christ-followers.
I'm not saying you are stupid. But for some reason, when it comes to contentious issues such as this, you and others like prefer not to know much, if anything, about subjects you are told to oppose.
I have five different versions of the bible bookmarked so that when a Christian makes a point and refers to a biblical verse, I can easily go to it and read their source. Christians aren't even willing to go to a frickin dictionary and make an effort to understand what a theory is.
It's all in how one understands the words "theory" and "fact". For me, if you mean that you have made an assumption, repeatedly tested the assumption, and got the results you were expecting consistently, then you no longer have a theory but instead you have substantiated something that can be referred to as a fact. That's the way I was taught in school in evolutionary, godless public school science classes, so if it is wrong, don't blame it on me being a theist, because that dog won't hunt. But to make you happy:
From Webster's 1828 Dictionary:
THE'ORY, n. [L. theoria; Gr. to see or contemplate.]
1. Speculation; a doctrine or scheme of things, which terminates in speculation or contemplation, without a view to practice. It is here taken in an unfavorable sense, as implying something visionary.
2. An exposition of the general principles of any science; as the theory of music.
3. The science distinguished from the art; as the theory and practice of medicine.
4. The philosophical explanation of phenomena, either physical or moral; as Lavoisier's theory of combustion; Smith's theory of moral sentiments.
Theory is distinguished from hypothesis thus; a theory is founded on inferences drawn from principles which have been established on independent evidence; a hypothesis is a proposition assumed to account for certain phenomena, and has no other evidence of its truth, than that it affords a satisfactory explanation of those phenomena.http://1828.mshaffer.com/d/search/word,theory
FACT, n. [L. factum, from facio, to make or do.]
1. Any thing done, or that comes to pass; an act; a deed; an effect produced or achieved; an event. Witnesses are introduced into court to prove a fact. Facts are stubborn things. To deny a fact knowingly is to lie.
2. Reality; truth; as, in fact. So we say, indeed.http://1828.mshaffer.com/d/search/word,fact
And owning 5 Bibles is ok, knowing what is in it is even better, but that still don't mean you get it. Take no offense at this, but it's like the idiot savant who can play the piano by ear or do square roots in their head. It's nifty and a novelty, but has no real substance. You can know the Bible backwards in 5 different languages (and that would mean you are highly intelligent) but it wouldn't mean that you actually understand the Bible.
