What happened
However, around 3.8–3.6 billion years ago, it may have looked very different. Geological and mineral evidence suggests that, in its distant past, the planet experienced periods warm and wet enough for water to exist on its surface, potentially forming rivers, lakes and even an ocean in the northern hemisphere.
