If we reject the existence of the hand that made us, do we in fact ultimately exist?

Today I saw a window frame, divided into four separate panes of glass which I believe represent the four perspectives we can employ in life - of God, Jesus, Holy Spirit and our own. Even if we acknowledge God as our Creator, we can then completely ignore Him in our lives and ignore Jesus as God in the flesh and who then sent His Spirit to reside within us. Prophet Isaiah warns us: "Woe to those who quarrel with their Maker, those who are nothing but potsherds among the portsherds on the ground. Does the clay say to the potter, 'What are you making?'. Does your work say, 'The potter has no hands'. (Isaiah 45:9-10). We can choose not to believe our existence is the achievement of a creator or we can ignore our Creator, seeing our Creator as not knowing what is best for us. In fact, God does not see us as broken pieces of pottery but as His creative masterpieces. Let us look at Life through all three lenses of the Trinity who have lovingly created us and through our lens in that context. If we do not believe our Maker exists , then do His creations ultimately exist?
