Comments by "Winston Smith" (@kryts27) on "Where Did Water Come From?" video.

  1. Has anyone thought re, water on Earth: 1. Very early forming Earth formed further out from the sun than thought, then the early earth migrated towards the sun, 2. The very early sun was cooler than it is now, allowing ice in the Earth's current orbit, 3. Earth has significant water in the mantle, partly due to mineral formation there (now significantly extruded via volcanic eruptions). 4. Estatite is a significant mineral in the upper mantle and crust of the Earth.
