The first and most obvious reason for a human being to believe in God is existence itself—the fact that anything exists at all.
Everything we see, from the vast universe to the complexity of life, points to the necessity of a cause beyond itself. Philosophers and theologians have long argued that something cannot come from nothing. The very fact that we exist, that the universe is fine-tuned for life, and that consciousness itself is even possible suggests a cause greater than the material world—a Creator.
This is often called the "First Cause" or "Prime Mover" argument (from thinkers like Aristotle and Aquinas). It suggests that since everything in the universe has a cause, there must ultimately be an uncaused cause—something eternal and self-existent—that brought everything into being. The Bible expresses this foundational truth in Genesis 1:1:
"In the beginning, God created the heavens and the earth."
Atheists may try to explain existence through random chance or self-creation, but these explanations fall short because randomness doesn’t create order, and something cannot create itself. Belief in God provides the most reasonable and satisfying explanation for why anything exists at all.
Would you agree that this is the most compelling starting point? Or would you emphasize another reason first?

That makes sense. What would be your second best reason?

The second most obvious reason to believe in God is the existence of moral law and human conscience.
Every human being, regardless of culture or background, has an innate sense that some things are right and others are wrong. We universally recognize concepts like justice, love, and kindness as good, while cruelty, murder, and betrayal are wrong. But where does this moral law come from?
If we were just highly evolved animals, shaped only by blind chance and survival instincts, there would be no objective moral values—only preferences or social conditioning. Yet, deep down, people recognize that moral truths exist independent of human opinions. This is what C.S. Lewis referred to as the "Moral Law" argument in Mere Christianity. He pointed out that when we argue about what is fair or just, we are appealing to a moral standard that exists beyond us.
The Bible affirms this in Romans 2:15:
"They show that the requirements of the law are written on their hearts, their consciences also bearing witness."
This moral order suggests a moral Lawgiver—God—who is the source of absolute right and wrong. Without God, morality would be just a matter of personal or cultural opinion, yet we all live as if morality is real, objective, and binding.
Would you agree that the moral argument is a strong second reason? Or do you think another reason takes priority?

I like that answer but it's not as obvious because you have to actually think about it to understand it's significance. I’m looking for the best most obvious reasons, what would you see as the next best reason?

I see what you mean! The first reason (existence itself) is immediately obvious—you don’t have to think too hard to realize that something can’t come from nothing. So, for the next best reason, I’d say:
