Answer:
The answer to the question: There is a very wide range of estimates of the population of American Indias in the U.S at first contact, would be: True.
Step-by-step explanation:
When the first Europeans came into the Americas, be it North, Central, or South America, what they stumbled upon was a land that was not inhabited in the least. On the contrary, they saw islands and three continents joined together by small stretches of land that were populated by varied groups of indigenous people. These people were called later on Natives, or Native Americans, or simply Indians. By the time of Christopher Columbus´s arrival into the New World, in 1492, today historians estimate that there were, in the whole of the Americas, around 50 million people already living in the lands. And in North America alone, historians now know there were around 10 million people living in what is today the U.S and Canada. This is why the answer is true.
