Arguments for the existence of God

Many arguments for the existence of God have been made over the years. These arguments include:

The Anthropic argument Focuses on basic facts, such as our existence to prove God
The Christological argument is specific to Christianity: asserts that Jesus Christ's life as written in the New Testament establishes his credibility, so we can be sure of the truth of his statements about God.
The Cosmological argument, which argues that God must have been around at the start of things in order to be the "first cause"
The Majority argument: people in all times and places have believed in God, so who are you to disagree?
The Mathematical argument this defines God as the Absolute Infinite, a mathematical concept.
The Moral argument: argues that morality cannot exist without God, therefore God must exist
The Ontological argument, based on arguments about the "being greater than which nothing can be conceived".
The Pantheistic argument Defining God as All, it is similar to panentheism and cosmology
Pascal's argument uses game theory to show that belief in God is the best and safest strategy.
The Teleological argument, which argues that since the universe is highly non-random, it must have been designed by an intelligent designer, God
the Transcendental argument, which argues that logic, science, ethics, and other good things don't make sense if there is no God. Therefore arguments against the existence of God must ultimately refute themselves if pressed with rigorous consistency.

In addition to these formalized arguments, there are innumerable informal reasons people give for belief in God. For example, have had personal experiences with God, or revelations. Some attribute to God some intense emotions experienced, or striking insights gained, in response to prayer or worship. And some attribute the manner in which events in their lives have unfolded, or fortuitous coincidences in their lives, to the influence of God.

The theological standing of arguments for the existence of God is also subject to some debate among believers. Within the Christian tradition there are two sharply opposed viewpoints. The Catechism of the Catholic Church, following the Thomist tradition of St Thomas Aquinas, affirms that it is a doctrine of the Roman Catholic Church that God's existence can in fact be rationally demonstrated. Other Christians in different denominations hold similar views. On the other hand, some believers hold a contrary position. These believers note that the Christian faith teaches salvation is by faith, and that faith is reliance upon the faithfulness of God, which has little to do with the believer's ability to comprehend that in which he trusts. In other words, if Christian theology is true, then God's existence can never be demonstrated, either by empirical means or by philosophical argument. The most extreme example of this position is called fideism, which holds that faith is simply the will to believe, and argues that if God's existence were rationally demonstrable, faith in His existence would become superfluous.

There are also several arguments against the existence of God. The most common one is the problem of evil.
