how did the hadean eon get its name
Hadean "Hadean" (from Hades, the Greek god of the underworld) describes the hellish conditions then prevailing on Earth: the planet had just formed and was still very hot owing to its recent accretion, the abundance of short-lived radioactive elements, and frequent collisions with other Solar System bodies.
Esau Genesis 25:25 narrates Esau's birth, "Now the first came forth red, all over like a hairy garment; and they named him Esau."[11] The meaning of the word "Esau" is disputed. It could be related to the Arabic root ġšw, meaning "to cover."[12] Others have noted the similarity to Arabic ’a‘tay meaning "hirsute".[13] In Hebrew, the word "hairy" (Heb: se’ir) is a wordplay on Seir,[10] the region in which he settled after being 40 years of age. The name Edom is also attributed to Esau, meaning "red" (Heb: `admoni);[10] the same color describing Esau's skin tone.[14] Genesis parallels his redness to the "red lentil pottage" that he sold his birthright for.[15][1] Esau became the progenitor of the Edomites in Seir.
