You know the smell dirt makes when its wet? It's called petrichor and humans can smell it better than sharks smell blood in the water. It is detectable by the human nose at 0.4 parts per BILLION. This gave early humans a huge advantage in finding water when needed. https://en.m.wikipedia.org/wiki/Petrichor

    There is an Indian perfume base called Mitti Attar which tries to replicate this smell. It's like damp moss at first scent, then develops into rain on hot sand. It is entrancing. Proper Mitti Attar sells for thousands and takes years to make.
