🌍 The Theia Impact — How the Moon Was Born

Added: 2026-05-20

[00:00:00]Do you know that our moon was created when a Mars-sized planet crashed into early Earth and the collision nearly destroyed everything. 4.5 billion years ago, a protolanet called Thea struck the early Earth in a glancing blow. The collision was so violent it melted both bodies entirely. Debris was flung into orbit and coalesed into the moon within centuries. Without this catastrophic accident, Earth would have no moon, no stabilized axial tilt, no regular seasons, and likely no complex life. The moon is a monument to the impact that made Earth habitable. The moon was born from a catastrophe that nearly ended Earth before life even began. Every time you look up at it, you're looking at the scar of the collision that made your existence possible.
