The Sioux tribe believed in the god Wakan Tanka.
The Sioux people believed that human beings, animals, and trees were all created by the Mother Earth. They believed the Wakan Tanka, the Great Spirit, created the universe, and yet was the universe. The Sun, the Moon, the Stars, the Earth, the very rocks, and the human soul were all creations of the Wakan Tanka.

Yes, the Sioux believed that their "soul" was immortal, and that it would live on in the tree's, wind, clouds, sky, and nature. If a Sioux warrior fell in battle it was believed his soul was taken by the Wakan Tanka and he would be reincarnated in one form or another.
The Sioux and their religion are important to them and to what they believe in, they believe in the Great Spirit (Wakan tanka), the circle of life and the sun dance and so on. In my opinion I think that the Sioux are really actually religious, this is because they do religion practices and have many beliefs and following it in a prescribed sequence.
