can you imagine what it would look like if earth had rings like satyrn?
https://en.wikipedia.org/wiki/Bifröst
In Norse mythology, Bifröst pronunciation (help·info) (Bifrost in Scandinavia) or sometimes Bilröst, is a burning rainbow bridge that reaches between Midgard (the world) and Asgard, the realm of the gods
The bridge is mentioned in the Prose Edda books Gylfaginning and Skáldskaparmál, where it is referred to as Bifröst. In chapter 13 of Gylfaginning, Gangleri (King Gylfi in disguise) asks the enthroned figure of High what way exists between heaven and earth. Laughing, High replies that the question isn't an intelligent one, and goes on to explain that the gods built a bridge from heaven and earth. He incredulously asks Gangleri if he has not heard the story before. High says that Gangleri must have seen it, and notes that Gangleri may call it a rainbow. High says that the bridge consists of three colors, has great strength, "and is built with art and skill to a greater extent than other constructions."https://en.wikipedia.org/wiki/Bifröst#cite_note-FAULKES15-8
Seeing as you've gotten too "deep" into this to make debating most of these issues worthwhile, I'll just add this for flavor:
