This is completely FALSE. Blue and green (and grey) eyes come from the Nordics, who already had a civilization on Mars millions of years ago. They were hybridizing with brown-eyed humans during the entire Atlantean epoch that ended around 12,000 years Before Present.
All blue-eyed people on Earth descend from a single common ancestor.
One person had a mutation 6,000–10,000 years ago that switched off melanin production in the iris, creating blue eyes for the first time. That trait spread because it was considered attractive.
Green eyes are even rarer, while brown was the original human eye color.
A 2008 University of Copenhagen study confirmed that nearly all blue-eyed people share the exact same mutation in the HERC2 gene — strong evidence of a single founder.
One tiny genetic change in one individual thousands of years ago created a visible trait now carried by hundreds of millions of people today.
