I say: Look on the story from every side! You are explaining things you don't have a clue about! If you ask why there are so much bad things, I ask you, if you have ever looked at the millions of people that are happy with their belief and their relationship to god and believe in him. People just question god because of the bad and do not see the good things he does.

2000 years ago in the christian bible (referring to this, coz it's my religion!) he clearly stated why we have to suffer from that and we committed a sin. That is the reason why we are not in paradise and why pain, sorrows and hate exist. If you read further on (it is an amazing book by the way) he also stated that this will be over for those who are willing. The punishment of living in an non-paradise environment is timely, he even provides us instructions how to get back to paradise.
If you say: Yeah, that is a book with fairy tales! Why do you believe in scripts from the greek philosophers on which the western society is based in its values? Where is the difference?
