The History of Earth's Moon: How a Disaster Created Life & the Moon

According to the "Giant Impact Hypothesis," Earth's Moon formed from the aftermath of a catastrophic collision between Earth and a Mars-sized object called Theia approximately 4.5 billion years ago. The impact vaporized and ejected a vast amount of debris into orbit around Earth. Over time, this material coalesced to form the Moon. While the exact mechanism is still debated, the Moon's formation played a pivotal role in the development of life on Earth. Its gravitational pull stabilized Earth's tilt and rotation, creating more favorable conditions for life to emerge and evolve.
