Everyone... very interesting, care to name a few examples?
Who did the Germans learn it from then? Do you think it's some infinite loop?
While I am naming examples, I can't seem to note any from you.
'Some other event' or 'some other nation' is not really clear proof is it?
Also I don't see why this is a stupid argument, just because Germany learned it from 'another event in history' as you claim does not mean Turks couldn't learn it from the Germans does it?
