Rafael "Rafa" Nadal Parera is a Spanish professional tennis player, regarded as one of the greatest players of all time
In a July 16 2010 Sports Illustrated interview Nadal was asked "Do you believe in God? We see football players crossing themselves. You don’t do that. Do you do praying?"
Rafael Nadal: It’s hard to say, “I don’t believe in God.” I would love to know if God exists. But it’s a very difficult thing for me to believe. I don’t know. It’s private and I don’t want to speak about it, but I say, “If God exists, you don’t need [to cross yourself] or pray.” If God exists, he’s intelligent enough to [do] the important things, the right things.
In an interview for the Spanish newspaper Informacion, he answered this when asked about his view on wars:
Rafael Nadal: "Almost every bad thing that happens in life comes from some form of radicalism, it only unleashes problems that should be fixed. You are entitled to have your likings, sympathies, beliefs, but you should always respect the opinions of others, never insult them. The same happens with religion. You can be religious, or atheist, christian, muslim... whatever, but I think the atrocities that people commited in the name of religion are too much. For me, religion is the main cause of mortality in history".
