Raindrops form from water that has evaporated. When water evaporates it leaves behind whatever might have been dissolved in it. Hardness is caused by dissolved minerals (mainly calcium) in the water. Since rain comes from evaporated water, free from minerals, rain water will be soft.

as rain water falls,it is naturally soft.however as the water makes it way through the ground and into water ways,it picks up some minerals like lime and chalk and mostly calcium and magnesium ..so ya since hard water contains essential minerals..it is sometimes preferable drink water tho..
