What is the clearest proof of God's existence?

After accepting the credibility of human thought, the most important subject that should be examined is God as the creator and administrator of existence; and considering the abundant influence of this belief on the perspective and way of life of man, we should not be careless and credulous in accepting or denying it.

Although several arguments have been presented for explaining this idea and from philosophical arguments to invoking nature or the guidance of saints have been placed as the basis for belief in God, but attention to the criticisms of these arguments creates debates and ambiguities that do not end easily.

But if instead of searching for a human-like creator alongside or above other beings, we pay attention to the clearest truth we know, namely the concept of existence and its independence from external support, we will find God more evident than anything, everywhere and even within ourselves.

For this purpose, it is sufficient to pay attention to the obviousness of this point that the totality of all realities of existence does not take its existence and perfections from other than itself, and this self-sufficiency is not possible except with possessing infinite perfection. This point leaves no doubt in the existence of an independent reality.
