There's no such thing as "European" or "Middle Easterner" DNA. These groups aren't homogeneous and I'm not sure what you mean with "look European", since they can vary a lot in their looks.

These people look more or less alike because they share similar origins. It seems that most human groups that made their way into Europe originated in the Middle East or Western Asia. That being said, it is now clear that some of these groups remained isolated from one another for thousands of years, and people that lived in the Middle East 9,000 years ago were genetically different from present-day Middle Easterners.

In addition, some traits like blond hair, blue eyes and fair skin are determined by relatively few genes. This means that a person with blue eyes and/or fair skin does not necessarily carry high levels of 'white' ancestry. In fact, many people in West Asia have light eyes and they're not that closely related to Northern Europeans.

That absolutely not true. Some Levantines such as Lebanese have European DNA dating from the Roman times!!!!

Because "Europeans" are middle easterners who migrated into Europe and mixed with central asians. There's only 10% original European HG in European DNA.

Europeans and Middle Eastern people DO actually share similar types of Dna; THEY ARE BOTH CAUCASOID PEOPLE. There will be different mutations in the DNA showing where the different groups branched out and travelled thousands of years ago. Europeans came from the near and Middle East!

Common origin. In paleontology and archaeology, the Danubian corridor or Rhine-Danube corridor refers to a route along the valleys of the Danube River and Rhine River of various migrations of Eastern cultures from Asia Minor, the Aegean region, the Pontic-Caspian steppe, etc., into the north and northwest of Europe.

Europeans evolved from Central Asians, who had migrated out of Africa 60,000 years ago. The Central Asians who migrated to Europe did not do so until 40,000 years ago. Europeans evolved their distinctive traits, such as light skin tone, thin lips, tall and narrow nose bridges, shorter arms and legs, rounded torso and increased facial and body hair, as adaptation to the cold, ice age climate of ice age Europe. The Levant is the region that includes countries like Jordan, Lebanon, Syria, Israel and Palestine, NW Saudi Arabia, and western Iraq. People from this region would not have evolved traits like light skin, tall and narrow noses or more facial and body hair, since such traits are not adaptive to their region. If people from the Levant region have these European traits, then their ancestors probably came from Europe.

In addition to not having a clue about DNA, what else don't you have a clue about?

Nationality is not a matter of genetics. It is not determined by DNA, and no such conclusions can be reached by looking at DNA results.
