I would want to know, honestly, what reason there really is to believe in Buddhism at all. It is an entirely man-centered religion, and it is not concerned with answering any of the great questions about who or what we are, or the nature of the universe. In the Buddhist texts, the Buddha is famously evasive of such questions, saying they are irrelevant. Sure, there is a basic recognition that there is an unsatisfactory dimension to this changing world, and that latching onto unchanging things is harmful and does not lead to satisfaction, but that doesn't affirm Buddhism's truth, it merely means that the Buddha makes a true insight (and this same insight has been repeated in numerous religious traditions). Christianity is utterly superior to Buddhism, because of the historical evidence we have for the Bible, its prophecies fulfilled in Christ, and the fact that the Scriptures continue to come true today. The Fall of Man explains everything we see, and it is clear that God is in control of human history, and that the world we live in is a product of intelligent, purposeful design. God created us to come to know him, and to have faith in him, and love him. This is the 'suffering' we feel, when we do not know Jesus Christ. Buddhism is ultimately about saving yourself, and making yourself your own Christ.
