When it rains - well, some people get annoyed because the sun would be the preferred weather option. But assuming it didn't rain: what alternative would there be to moisten the soil in this way? Irrigation from the ground would be infinitely complex, a whole irrigation system, a drainage system would have to be invented. But this way, the clouds can simply let go of their moisture and the falling water is distributed everywhere. Ingenious. You don't even think about it. But why is it so easy? Among other things, because of gravity: if it weren't for the Earth's gravitational pull, the water from the clouds - yes, it would just stay where it was released - wouldn't be literal precipitation, but water at rest. One would then have to invent some method for this moisture to get to the ground. Again: infinitely complex. How good there is gravity, clouds and rain. An ingenious concept. Hats off!
I wish you an extraordinary day!
