Rain first appeared on Earth approximately 2.7 billion years ago, during the Archean eon. This occurrence was closely tied to the cooling of the Earth and the formation of the early atmosphere, which enabled water vapor to condense and fall as rain. This pivotal event played a crucial role in shaping the planet's surface, aiding in the formation of oceans and setting the stage for the emergence of life.
