Hi Rebel. I was never a Witness but I was brought up as a Christian (Catholic). I left that faith because I didn't believe in a god anymore. This is fairly typical of ex-Catholics but it seems that many Witnesses leave their religion but, initially at least, remain as Christians.
I agree with freemindfade that it's key to accept that humans don't know everything, but are learning more and more. Don't be tempted to attribute things we don't understand yet to god.
Regarding intuition - our sun is one star in a galaxy of at least 100 billion stars. The total number of galaxies has been estimated as up to 10 trillion. How likely is it that any god would take a personal interest in our lives? My intuition says very, very unlikely.
