Believe or no belief?

Does God exist? No one has absolute proof. We can neither prove nor disprove God’s existence. While some believe in a God because they cannot imagine that this gigantic universe came into being by chance, others think it is more likely that nature came into being out of nothing without a cause.
God could simply appear and prove to the whole world that He exists. But if He did that, faith would no longer be necessary. “Jesus said to him, ‘Thomas, because you have seen Me, you have believed. Blessed are those who have not seen and yet have believed!'” (John 20:29).
