I guess I'll try to tackle this one. First of all nowhere does "science" say that you can't create something out of nothing. Modern cosmology theories seem to indicate that that is exactly what happened to create the Big Bang. If matter and antimatter can annihilate each other to nothingness, so too might they be created out of nothingness.
Even if no good theory existed to explain the creation of matter, it does not prove that a creationist theory is better. Creationists say God created matter, but don't worry about explaining where God came from.
Oh and regarding "simplizing". I think the word you are after is simplify.
