Are there aliens already in Poland? What do Polish people think about extraterrestrials?

Poles don`t worry! Superman is Serbian and he would protect you from aliens

I think therefore I am. People invented that one a few millennia ago. Keep up with time.
That's all I've got.

edit: unless you claim not to "think" at all than you've proven your point.

There are aliens in Poland

if alive Adolf or archduke Ferdinand could say: `Poles are aliens in Poland`

fortunately, there are Serbs who proving that Germans represent aliens of Germany and Austria
