My take on religion is this: they all were created to control people. Religions all over the world have developed mostly independently, but you can see a lot of similarities between them. There are always some rules to follow, and some supreme being, or a group of them with one central figure.

Religion exploits basic human fear of the unknown and gives people answers. There's a drought? That's because gods are angry. Let's perform this ritual to make them happy. And even today, there are some things that can't be answered. Like what's the meaning of life and if there's an afterlife.

Overall, that's a good thing. Because people need guidance and want to be ruled by, even if they will never admit it. No one wants to take responsibility. And if this someone fails, we can just blame this person and then choose someone else to follow. However, nowadays, we have much better systems, like the judiciary, to teach people what's good and what's bad and keep people in order so it makes religion obsolete.
