I am not antheist, I am just a non-believer

Just dont like that word, it's not accurate and it's hideous. Science is not something to 'believe', god doesnt exist, human doesnt have 'soul' isnot something to 'believe'. Science is something you can challenge, understand and prove, while religion isn't.

Why some people believe in bible, some people believe in kran and some believe in other books? Through out those books, there is evidence showing it's written by human. Which book to believe in? why that book? follow the heart? sorry, my heart doesnt 'think', I follow my brain only.
