Being able to smell fresh rainfall must have been pretty useful in the dry environments humans evolved in. Bonus fact, geosmin is produced by soil bacteria to attract tiny insects called springtails to eat them and spread their spores. But it also attracts us!

We can see signs of water much easier and longer than we can smell them. Just look at the ground, maybe scratch away the dry dirt on top.
