I saw a Science Channel documentary last evening about the pre-Columbian “discoverers" of America (both North and South). They made quite a case for two separate migrations around 20,000 BC. One was the traditional Aleutian land bridge of northern Asians and the other, at about the same time, from Europe. The Europeans became the ancestors of the Cherokees of the south eastern US. The two cultures eventually merged to become the Clovis culture throughout North America.
They also included at various time periods and with various degrees of credibility the Polynesians, Chinese, Japanese, Irish, Egyptians, Vikings (of course) etc.
I think if they could have made a case for the Martians, they would have included them.
