Scientists generally agree that our world had a beginning. And that beginning had to be contingent on a thing that was not contingent on anything else for its existence. Therefore, that noncontingent entity had to be infinite, eternal, everlasting, and self-existing. It had to be God. The purpose and design of the world point to the existence of God.
Physicists marvel at the unbelievable complexity of everything they study.
Yet it all fits together in an intricate, workable system. Consider the fragile balance of heat and cold, the delicate mix of oxygen and other gases, the thin curtain that shields us from ultraviolet rays, the complicated relationship of the parts of the ecological system to each other. They point to intelligent design. This reasoning is based on the nature of the human personality. When we worship, we are able to think abstractly and to project ourselves mentally into the world beyond.
