What do you believe is true, even though you cannot prove it?

I believe we are here for a reason(I cannot prove for what reason).I believe the world is knowable and I believe we will one day be able to find out all answers to all questions(and at that time we may well be transcendental and timeless).I believe God has nothing to do with what the Bible says about him.I believe that life is common throughout the universe and that we will find another Earth-like planet within a decade.I believe everything happens for a reason.I believe the universe does not split on every possible interaction creating infinite universes, in some of which Saddam Hussein is friends with G.W.Bush or Bin Laden is fighting against islamists.I believe the most beautiful girls in the world live in Russia, Ukraine, Bulgaria and Thailand.Edited by Agobot, : No reason given.Edited by Agobot, : No reason given.
