He first investigated Christianity, and all time he got more questions and all answers he got from Christians were all personal answers. The Bible has so many interpretations. What is the deal with the Elephant head guy in Hinduism? He explored that religion too. He went into the religion of Mormons and he did not have enough proof to accept that religion either. He did not find what he was looking for. He finally found Buddhism, the pace and the One with the world. He also found that it was not a religion of God, only a nice way to live.
Then he thought about Islam and he only thought that he did not want to become a terrorist so why even bother to explore that religion...
