Hinduism and Buddhism are also presented. This is followed by exploring Monotheism. Judaism imposes human characteristics on God and present Biblical Prophets in a corrupt manner, which exposes the grave defects in the Old Testament. The four phase theory of the Evolution of Christianity in its first 800 years reveals how humans, not Jesus Peace bee upon him, formulated the doctrines of Christianity.
