How come it only rains when you forget your umbrella?

Because there is a god and he's a dick. No not God like in the Bible there is no all powerful god, there is only a rain god. He can't control anything except the rain. Every other force of nature like light, fire, stars, love, the sky, the sea, the seasons, life, and the creation of the universe are caused by purely scientific explanations exactly like atheists think they are. There are no such thing as souls and there is no afterlife. There are no monsters, demons, witches or angels. There are no other gods there is only one god, the rain god. Yes he is male, goddesses don't exist. No he can't control the weather like snow, hail, or storms just rain. No he is not the god of all water just rain.
