The questions that The Blackfoot Myth answer's, and the Apache Myth does not is:

"How were trees created?"
<u>Explanation:</u>
The Blackfoot tribe and the Apache tribe were a tribe of Native Americans, though spread out in different regions of the country.
The Blackfoot tribes were to be found primarily in the great plains, which include Canada, Alberta, and Montana. Mostly the colder regions.
The Apache tribe was primarily to be found in the plains that are in the southwest region, which is New Mexico and certain places of Arizona.
According to the Blackfoot mythologies, they believe in a mystical "Napio", who, they believe, created the earth, the grass, the trees, and almost everything that is on earth.
According to the Apache tribe, they believe mostly on the creations of the mountains and believe that the mountains are the wall of the world, inside which they live.
Hence, this way the Blackfoot believe in the creation of the worlds and other existing things, which the Apache tribe believes in the existence of the mountains.
