Does Proof for the Existence of God Have to be Complicated?

God, at sundry times and in diverse manners, was in time past defended by apologetical writings of theologians of the Christian religion. These theologians delivered arguments that ranged from the absurd to the complex, but each was aiming at a sophistication that could be appreciated and respected by the philosophically astute. But does the proof for the existence of God have to be sophisticated and complex? Does it have to rise to the level of satisfying the philosophically astute? Alvin Plantinga, no mean philosopher, gives this reply in an interview when he is asked why he believes in God:

In my case it's like asking, why do you believe there are other people? Why do you believe there's a past? I can't give a proof that there's been a past, or a proof that there are other people, just as I don't think the traditional arguments for God's existence. . .I don't think that they are all that powerful, although. . .although they do have some force. But it just seems to me right. It seems to me that there really is such a person. When I contemplate, when I think about, or, say, when I look at the mountains, when I look at tree tops in my backyard, when I go to church, when I read the Bible, on many other occasions I just found myself convinced that there is such a person as God.

Keep in mind that this statement is from one of the leading Christian philosophers in the nation, who has delivered one of the most compelling and complex arguments for the rationality for belief in the existence of God and has successfully shown that there is no logical inconsistency between the existence of an all-powerful, all-loving God and the existence of evil. Yet his rationale for belief in God boils down to this simple statement of faith. It's not surprising, though, that such a brilliant mind can find rationale for belief in God by contemplating the things around him. He is a creature created by God in the midst of the entire universe that was created by God. Belief in God is really as simple as opening your eyes, or, more correctly, having your eyes opened.
