Does God exist, and How can we know?

Two basic types of evidence are utilized to answer this question, Faith and Reason. Faith is a phenomenon available to all people and is present in various degrees of development in each person. Reason is available to all human beings to a variable degree as well. In excess of 20 classical arguments have been developed over the past several thousand years by scholars in an attempt to demonstrate the existence of God. These "proofs" based on reason, can establish with a high degree of probability ie., >95% likelyhood, that God exists. They will never be able to demonstrate it with 100% certainty since God is a transcendent entity and by definition exceeds our human ability to define, prove or otherwise characterize. Faith can provide an additional degree of certainty which is not quantifiable, and is dependent upon a personal interaction between God and the believer. Together faith and reason provide for cognitive certainty that God exists.
