Each of my science books said, “This is why we think this; this is how we figured it out; and this is what we still don’t know.” That I can trust. An… - Aron Ra

We don’t believe this because we want to! And why would we want to? We believe it because we can prove it really is true, and that applies to everyone whether you want to believe it or not. We’re not just saying you’ve descended from primates either; we’re saying you are a primate! Humans have been classified as primates since the 1700s when a Christian creationist scientist figured out what a primate was –and prompted other scientists to figure out why that applied to us. It wouldn’t be this way if different “kinds” of life had been magically-created unrelated to anything else; not unless God wanted to trick us into believing everything had evolved. Because the phylogenetic tree of life is plainly evident from the bottom up to any objective observer who dares compare the anatomy of different sets of collective life forms. But it can be just as objectively confirmed from the top down when re-examined genetically. This is why it is referred to as a “twin-nested hierarchy”. But there’s still more than that because the evident development of physiology and morphology can be confirmed biochemically as well as chronologically in geology and developmentally in embryology. Why should that be? And how do creationists explain why it is that every living thing fits into all of these daughter sets within parent groups, each being derived according to apparently inherited traits? They don’t even try to explain any of that, or anything else. They won’t because they can’t, because evolution is the only explanation that accounts for any of this, and it explains it all.

If you can’t show that it’s true, then you can’t call it truth. Knowledge is similar to truth in that it a justified belief. Knowledge is demonstrable and testable with measurable accuracy. If you can’t demonstrate your knowledge to any degree at all by any means whatsoever then you don’t actually know what you think you do, no matter how convinced of it you are. Without evidentiary support, then it is only an empty assertion unworthy of serious consideration.

Every religion claims to believe as they do because of reason, education, or intelligence given by their god in revelation. But whether they admit it or not, all of them are assuming their preferred conclusions on faith, and this would still be true even if all of their gods exist. Believe as hard as you want to. But convincing yourself however firmly still can’t change the reality of things. Seeing is believing. But seeing isn’t knowing. Believing isn’t knowing. Subjective convictions are meaningless in science, and eyewitness testimony is the least reliable form of evidence.
