If there really has been a beyond top secret black project trying to accomplish this, it almost certainly has failed, and that's why we don't see any alien technology suddenly disrupting our civilization. In reality it would take humanity many centuries to understand and make anything at all out of that hyper-advanced technology thousands if not millions of years ahead of us.
That argument further supports the idea that there's no reason to keep alien artifacts secret, making the entire notion even more implausible.
