What resource is found on earth but not manmade?

One notable resource found on Earth that is not manmade is freshwater. This vital resource exists in rivers, lakes, and aquifers, and is essential for drinking, agriculture, and various ecosystems. Freshwater is naturally replenished through the water cycle, including processes like precipitation and evaporation, making it a critical component of the planet's Natural Resources. Its availability and distribution, however, can vary significantly across different regions.
