Why do humans need religion?

It is because human nature is religious, and people have a longing for infinity and eternity. From the biblical point of view, because people have souls, the material world can't satisfy our souls. Only God can give us satisfaction.

I remember Newton was a Christian very early. In fact, more than 80% of the great scientists in the world are theists. Many people think that science and religion are in conflict, but they are not. For example, Genesis in the Bible mentions that all things in the world and the laws of nature were created by God. Since these are all created by God, then God must be above the laws of nature and not limited by these laws. So there is no conflict. The so-called conflict is considered absurd, unscientific and contrary to science just because human reason cannot understand and explain some phenomena. This obviously confuses the concept. In fact, phenomena that cannot be scientifically explained can often be answered in the Bible. For example, the Cambrian biological explosion, such as chicken or egg, such as the Big Bang theory, such as why metabolism leads to human aging and so on.
