Unfortunately, even if a flying saucer is produced this would not prove that it had anything to do with aliens. It could be human built.

Can you fly it?  Nope.  Can anyone one Earth fly it?  Nope.

WHERE do you see one?!
where is your proof aliens fly it?
lots of kooks say it's the nasa ,cia or whatever.
and to fly one it must excist...until then...

The only way to prove aliens are here is to show us an alien.

Nope.  The incontrovertible proof is at S-4 Groom Lake,

go see it for yourself.

do it yourself and show it.
you have been there?
or just wishfull thinking?
and adding 1+1=11?
or    kooks stupidity+ fuzzy picture  = proof of aliens!
