Every new discovery, by definition, begins with new observations.
The word you're clinging to is "known". We've been spectacularly wrong in the past (the sun orbited the earth, which was flat, etc.).
As for history, there's no reason to suspect they would have made their presence known in any undoubtable manner. They may have been here just to observe.

Are you sure you are not adding epicycles to your model of reality? > “Any sufficiently advanced technology is indistinguishable from magic.” Clarke And yet no technology we ever seen actually IS magic or of alien origin. I'm not sure what's your point is? That alien tech might look like magic? Sure. But we have never observed any magic either in our world. So they both belong squarely in the world of dreams not reality.
