Some would argue that we HAVE used them...or at least things gained from them...such as the transistor, circuit boards, fibre optics, etc.
As for
the craft themselves...again, maybe they have? Not like we could tell from the ground whether or not a disc was piloted by Reticulans or American
pilots....
Of course, the bottom line is, we still need proof, and it needs to be global, undeniable proof, because anything less, can easily be dismissed and
covered up any number of ways...(and often is)...
