If matter cannot be created or destroyed, where did the first(present)matter come from?

Though, it is still a big question, if the "Big Bang" was reasonably symmetric the universe should have started out as pure energy, or as equal parts antimatter and matter (matter can be destroyed and turned into pure energy by combining it with antimatter, and energy in some other form can be converted into equal parts of matter and antimatter). The big question is, why do we normally only see matter around us, and not equal parts of both matter and antimatter? (Of course it would be pretty hazardous living around stuff that could annihilate you!). There are a bunch of theories, but as far as I know, nobody really knows yet.
