Challenging Beliefs or Ideas

       My friends' birthday is around Christmas.  I was attending his birthday party, And after the party was over me and a small group of friends were hanging out, sorta like the "after party" except more of a gathering than party.  This was about two years ago.  We were lying outside, on the grass, gazing at the hundreds of stars above us since we were away from the city lights in the suburbs.  Then Kyle, the birthday boy, asked us all if we believed that there was some sort of god or deity out there watching us, and if so, why?  We all thought about it, debated about it, and that's when my beliefs were challenged.  What is it that makes me believe that there is something out there?  The biggest argument saying a God exists was: "How did we come to be? How were we created and why do we have the intelligence to do what we do?" The biggest argument against the idea of a creator was: "Science says everything came from the big bang.  They have evidence of of the big bang from radio waves, and, according to these waves, the Milky Way is one of the oldest galaxies in the Universe. And if there is a God, what created it? 
       The result of that one night of questioning the existence of god is that I'm left doubting if there is one.  Sometime certain amazing, seemingly impossible things, will happen, and my faith is revived, but then I remember how miserable so many people are, and then I think, if there is a god, why is he letting this happen? So my faith is pretty rocky.
      The courage to challenge beliefs is important because sometimes if you don't challenge beliefs, you'll stumble blindly through life.  For example, if you live life with racist, sexiest beliefs and you don't stop for a moment and question, why do I believe this? Than you'll just be an ignoramus for the rest of your life.  Maybe if you question your beliefs hard enough, you'll find out what keeps you ticking everyday!
