Actually, no. I don't know anything about scientific knowledge. I'm pretty much simple. To try to answer your question, though, basically. If you are not certain of something, then that's just doubt. I guess it could be agnostic. From a outside view, it seems agnostics doubt the existence of God...they leave it open that He could exist yet will say, without proof, He does not.
I am kind of confused where you going with this.
I am 100 percent certain/I know that I am typing on a computer. (Unless we can philosophize and say "what if it's all in the mind?" or things like that) but without going through the exclusions or philosophizing and saying things like "what if we were just ants in a jar"). I'm just making a statement (not claim) I am on the computer.
I am not certain that you are a male or female. I believe that you are a male (which wouldn't matter in the conversation; point purposes only), but my belief doesn't make anything true. So, I can believe in something and still not be certain because belief is not claiming certainty.
On the other hand, knowledge is. It is saying I Know that you are a male. There is no room for uncertainty in that statement. (We can philosophize about it; but that's not my point) Is it true? If I know something, then yes it is true. It's a statement not a claim.
If I said "I believe you are a male and I don't know/uncertain" those two go together. It doesn't make sense to say "I Know you are a male and I am uncertain." Which is it, do you know or just making an assumption, belief, or claim? Are you certain or are you not? Type of thing.
It's not philosophy or what-ifs. Just saying that to state you know something is true means you are certain. To state you believe something is true does not always mean you are certain it is one hundred percent.
Makes sense?
Well, my point is that knowledge is not the same thing as absolute certainty. The latter can entail the former, but the vice-versa is not necessarily true.
If the two things were equal, it would not make sense to speak of things like scientific, hystorical, etc. knowledge, since science, for instance, is not in the business of certainties. After all, nobody would say that humanity acquired a lot of "beliefs" in the last centuries. Everybody uses the word "knowledge" in case of science without a problem althought only very few, if any at all, of our progresses in understanding reality qualify as absolute certainties.
Incidentally, it follows from simple logic that if we declare ourselves agnostic about God, then we should be agnostic about the (literal) God of the Bible, too. Ergo, we should be agnostic about the earth being 6,000 years old, which sounds kinda weird.
So, no, I do not believe that angels do not carry planets around. I know it, althought I cannot give you absolute certainty that angels do not indeed carry planets around. As implausible as it can be, the angels carrying planets scenario is still possible. Same with God, basically. Implausible, but still possible. But that does not prevent me from asserting to know that God does not exist.
Btw, what makes you believe that I am a male?
