How did the Indians view earth?

Answer 1

If you mean native Americans, every tribe was differentand each had its own mythology and world view. In general terms, there was absolutely no understanding of earth as a planet, nor of the world beyond the bits each tribe knew from their own experience. They had no concept of other countries or how their own land fitted into the complete picture.

In some groups, the earth was considered to be constructed on the back of a giant turtle (which accounted for the curve of the horizon), but this was not a belief held by all tribes. Some simply recognised the earth (meaning the solid ground) and the sky; water surrounded the earth because the solid ground was thought to be like a huge island, made by the Creator.

There are far too many different native ideas about the earth to explain them all here.
