I have met many people who think that a belief in God is like believing in Santa Claus. You must simply "just believe." While faith is the key aspect to knowing God, it is not blind. There are many great reasons for a belief in a transcendent, prime-mover, and Uncaused Cause.
1- The First Cause (Cosmological) Argument
Everything must have a cause, therefore the universe must have a cause, and that cause was God. God was the first or uncaused cause.
2- The Design (Teleological) Argument
The universe is wonderful and exhibits evidence of design and order. These things must have had a designer that was even more wonderful, and that designer was God.
3- The Argument from Life
Life cannot originate from the random movement of atoms, and yet life exists. Therefore the existence of a God was necessary to create life.
Don Stewart
4- The Argument from Revealed Theology
The Bible says that God exists, and the Bible is the inspired word of God, therefore what it says must be true. Therefore God exists.
5- The Argument from Miracles
The existence of miracles requires the presence of a supernatural force, or a God. Miracles do occur, and therefore there is a supernatural force or God.
Richard Swinburne
6- The Ontological Argument
God is, by definition, perfect. A necessary quality of any perfect object is that it exists. If it did not exist it would not be perfect. If perfection requires existence, then God exists.
7- The Moral Argument
All people have moral values. The existence of these values cannot be explained unless they were implanted in people by a God. Therefore, God exists.
8- The Wish Argument
Without the existence of a God people wouldn't have any reason to live or be good, therefore there has to be a God. Most people believe in a God, therefore there is a God.
9- The Argument from Faith (Pascal's Wager)
The existence of God cannot be proven by the use of reason, but only by the use of faith. The use of faith shows that there is a God, therefore God exists.
10- The Argument from Religious Experience
Many people have claimed to have a personal experience or encounter with God, therefore God must exist.
