Mexicans are -usually- darker-skinned and don't have green eyes. :o

I can tell you're still confused, so let me see if this helps you understand better.

The Americas were discovered recently, comparatively speaking. It was only inhabited by Native Americans (I guess you could say, the "real Americans") before people from other places (specifically Europe) started comin' in and takin' over. Today, people from all over the place are in America. Almost every single person is mixed. There is not one singular ethnicity that defines America.

Early on, the Spaniards conquered pretty much all of South America, so it was just them and Native Americans over there for a time. Mexicans are probably like a mix of the Spanish and the Native Americans...so it sorta became an ethnicity in itself. At least, I'm pretty sure that's how it goes.
