Are Indians immigrants from ancient China?

1. Because Europeans know that the earth is round, they came to America to the west, thinking that when they arrived in India, they called the locals Indians.

2. According to anthropological point of view, there are two main sources of American Indians. The first batch came to America from Alaska 400,000 to 500,000 years ago by a land bridge connecting Asia and America. They belong to the same race as the Malays in Southeast Asia. The second group came to Alaska from Asia through the Aleutian Islands or Bering Strait 20,000 to 50,000 years ago. They are Mongolians from East Asia, and both of them are yellow.

3. As a specific country, China was only formed in modern times. Ancient China refers to the Central Plains, a Chinese civilization that only appeared four or five thousand years ago.

Conclusion: American Indians came to America before Chinese civilization, so they can't be regarded as ancient immigrants from China.
