The San people and Norse people both have very similar creation myths. How can two cultures separated at both ends of the world have similar myths?

The people of the Early Race (Sans) throw the sun up into the air so the light shone through its arm pit illuminating the world. Just like Odin, Vili, and Vé killed the frost giant turning it into the Universe and everything we see. And a little girl from the Sans creation myth created the stars by throwing ash up into the sky. How can the culture of people separated at two ends of the world have very similar creation stories?

Even the Gods Kaggen and Loki are both described as Tricksters

For me this just goes to show how often I hear about one religion influenced another, because there's some aspects of both that are similar, but clearly it's a coincidence (and not much of one)
