Of course, Europeans originated in Africa like everyone on this planet.
And if we go back far enough in time, Europeans are also partly Neanderthal.
More recently, Europe has been populated by massive migrations from Western Asia (Caucasus), Central Asia (a vast area from India to Iran) and others.

Some new intakes from North Africa and Near-East.
And of course, Europeans have steadily traveled (trade, wars, scholars...) and mated everywhere within Europe.
The American romantic vision of Europe, therefore, makes no sense.
"I got my DNA test, and I'm 22 % Irish, 18 % English, 15% German, 12 % French, 6% Spanish, 5 % Jewish..". Even a French or an Irishman is already all of that plus many more!
How can you seriously trust those tests?
And yes you are also probably 5 % Native American (because Native is cool) and 1% Senegalese (just to piss supremacist off in case you're "white")
