Jumong's origin story reads like a Marvel movie and I'm not even exaggerating

Born from an egg. Mom got pregnant from sunlight. Raised in enemy territory. Could shoot arrows before he could walk (allegedly). Escaped multiple assassination attempts by his jealous half-brothers. Crossed a river that magically parted for him. Founded Goguryeo at 22. Died a king. If someone pitched this to Netflix they'd say "tone it down a bit." Nah fam, this is actual Korean founding mythology.
