Well sure, but at least in comparison with the entire history of life on this planet, we've known close to nothing until the last ~400 years and have since figured out most that practically matters to us on a daily basis. We don't know how to cure cancer, but we know exactly what it is.

We're certainly still wrong about exotic types of matter, gravity, fundamental particles, the ways completely arbitrary things function, like genes in a cell, etc... but we know that cells exist, what they're composed of, and we're definitely not wrong about that, and that is frankly infinitely more knowledge than we've ever had before. What's left to find are mostly increasingly more nitpicky details that are nonetheless very important, but they don't change our understanding anywhere nearly as drastically.

To wrap back around to my original point, in comparison to everything else the amount of knowledge we've gained on paranormal things since tribal shaman times is about zero. It's still all hearsay and speculation and it's not for the lack of trying.
