If Noah in the Bible was white where do Mexicans come from?

The Hispanic community of Mexico and South America comes from two or three different sources. Much of the original people of Mexico and South America are from Native American tribes that lived there. This includes the Incas and Mayans that dominated the area. Many of the descendants still show the features of these two peoples. There were other tribes that were spread through out the region ( some still exist). When the Spanish invaded and enslaved the people they took native women as wives and slaves. The offspring of these unions created what is called today "Mexicans". A combination of native Mexico and Spanish. Today the Spanish roots still shows up in the red hair of many people called "Mexican".
