Storytellers include the two twins in the creation myth.
We can arrive at this answer because:
The right and left twins are characters in the creation myth developed by the Iroquois.
According to this myth, these twins created the good and bad things in the world.
The right twin was responsible for the good things, while the left twin was responsible for the bad things.
However, the myth states that nothing is completely good and nothing is completely bad, with the right twin already showing bad attitudes and the left twin already showing good attitudes.
The myth also asserts that the balance between good things and bad things is essential for maintaining the world.
This balance reinforces the idea that the two twins are important and for this reason, storytellers should introduce both whenever they tell about this myth.
