Rain falls. That's what it does. But it doesn't do it always in the same way. Sometimes, rain feels almost extraterrestrial, as it fell not from the sky, but from some awful place, far in space. Other times, you would think it comes from a land made of candy, created for children or for people that love a nice piece of heaven in their mouths. Wherever it comes from, rain is one of those things that makes us feel truly alive, specially when it rolls down our faces and bodies.
Rain is water but it can also burn when the body it touches is not pure, full of guilt and all those pathetic human feelings that fester inside brain and heart. Water cannot wash way all of our evil. It's not acid, even when it feels like it. Some cannot feel all of its properties. There are people that could swim for hours and never feel clean, not truly. Hot or cold, the liquid is not enough to wash away everything that is wrong with the human soul, and humankind in general. People won't be saved.
Rain won't do It and nothing else will. On other worlds, it rains gasoline and diamonds. So we all have that in common: things will Jeep falling on our heads, no matter what we think about the universe. The brain might have an understanding of how mostly everything works but when we're all dead, that won't matter. Water will still be water and gasoline will keep falling from the sky unto someone else's head. And it won't matter if we were here, if we attempted to understand this place or not.
Rain won't care. Nothing will. Because we don't want to understand that se are all here for a little while. We were given some seconds on the clock of existence and that time will run out. No matter how much we try, we won't be here forever and our existence will leave no trace. No wonder or creation made by our hands will remain to tell our story. This scares us more than we want to admit, but that's how it works, no Gods in question. One moment we are here, the next we're not.
Rain, however, will stay. Until the very end.
