[Marvel Comics] How much of Norse mythology actually happened in the literal sense? Did Loki really give birth to the eight-legged horse Sleipnir? Was Burí, Odin's grandfather, really born from a cow licking a glacier?

In comics - yes, in MCU - no. And humans already know about Loki being bad and Ragnarok because of weird timeloop related to Ragnarok(like Kalpas in TES).
