You are an ignorant, atheist young kid. Some basic realities need to be remembered, and will be, soon enough. Without faith a whole part of your brain, of your biology, is dying, the limbic system that developed hand in hand with the birth of faith.
Faith is required to do good use of knowledges, or they ll end being used for destruction.
I'm not ignorant, I consider myself a highly educated individual with an IQ of 130+, and just like I've stopped believing in Santa Claus after I reached "The age of reason" (or to be more precise - when an information that is accurate/in tune with the reality replaced false beliefs), I've stopped believing in god, that's no more real then santa is, after I learned what religion is, what it's based on and how it arose back in the time. And I don't even agree with me being called an /atheist/, because if I'm an atheist, then I must be an /aSantaClaus/ either. Maybe we should think of some other names for people who for. ex. doesn't believe in "Alice from the wonderland"?
"Faith" means - assuming that some belief is right/truth, without being able to prove it in any way. From what history taught us - that /faith/ you are preaching as a "must" for a "good use of knowledges" (even tho' I'm pretty sure you wouldn't be able to explain in at least half rational way why is that so), was actually the cause of many destructive event in humanity.
There are few things more dangerous then a person who blindly believes in a "Holly book", which explains and proves itself (so there's no need for other "proof", or so think these who are brainwahsed by these holly books). Many wars were started on "faith" that one is right, and another is not, while not even trying to constructively solve the conflict. I wouldn't be too surprised if a new war would be based on the same old reason - different cinditioning of two different cultures (which are usualy based on "faith" as a central "value", faith in a "REAL" god, not that other, that "THEY" are preaching).. Oh wait... such wars are happening already...
