It'd be weird if it turned out that it is an alien aircraft and... that's it. It's too advanced for us to understand, it's too high tech. And we're left with, "Yup, aliens exist. No, we don't know anything more about them." It's like that old movie where an airline pilot drops a Coca Cola can into the midst of an uncontacted Amazonian tribe. "Wow, this thing sure is neat. Damned if I know what it's for though."
