@Kartlos: As said before you shouldn't look at history with our nowadays morals. Back in those days marrying a 12 year old was quite normal (in some area's). Being an atheist was something abnormal while nowadays it's not, maybe even the opposite. Morals are something that change very quick, and it's proven time and time again, by history. Look at Hitler, I'm not saying that he was the reason for the extreme hatred against Jews (and other minorities) but he did trigger the unleashment of it and used it for his own plans. While now we might think what he did is disgusting (we being the majority of the western world) but maybe in 500 the world has changed into a fascist place where they think what he did is good and he would be an international hero. I know it's hard, sometimes even impossible to look at history with an neutral point of view (something that is generally impossible) but it has to be done. Just saying that that man was bad because he did something that may or may not have been a normal thing back then makes no sense. It's like you save a cat tomorrow and everyone thinks you are a hero, and then 500 years later cats take over the world and every living human will think of you as a dirty traitor of the human race because of that same deed.

And on religion, barely anything in this world is proven beyond all doubt. Science, actually is just the same as religion. It provides a theory to explain things we don't understand. Just saying one is better than the other is total nonsense. Religion is not something that you can put in a box, nor in a book. It's a feeling, it's knowing without truly knowing it. It's something that most people need to survive, that little thing that gives that little amount of hope and power they need to make that last and final push towards their goals. Some people call their religion christianity, others call it Islam, you have people that believe in Science or communism. Yet others do it for those two little sweet blue eyes that stare at them from it's tiny little bet smiling it's teethless mouth. It's all the same, everything in life that you believe in without truly, beyond doubt knowing it's true but you still want to stick your leg out for it can be called religion. Even money can be a religion, that is why most people in the west don't have a standard religion anymore...
