Question for Evolutionists?

I'm a Christian and believe in creationism but I've heard several decent arguments supporting evolution.. I've never heard an explanation to two basic questions though.. Where did it ALL come from?? and somewhere along the line living things had to come from non living things to support the theory?? Isn't there a law that states matter is never created or destoyed it only changes forms?? So who created it to begin with?? How did it get there to get all "big banged" up.. and in the history of everything has there ever been a case where a rock, a particle of air, or clump of mud have ever "evolved" into something living?? If not.. why is it so widely believed that this is the case?
