Man, you are full of s***. Where did you get this information from, a klan rally?!?!?!?! The native tribes being from Asia has been a proven fact...but sir you will not have me to believe that Northern European tribesmen resided in common day U.S. before Native Indians sir. Oh sorry, you probably meant those Vikings landed common day Greenland...which is technically North America so they were here first and should be recognized as such.
People these days will often use whatever "proof" they find in a book or online and force it as truth. You mention "historians & scientists" as if its your proof. Next time, show receipts, Copy and paste your absurd claims so that I can go at the writer and not the misguided messenger.
