Do you realize that this statement is self-contradictory?
You don't even get your own philosophy. Either everything is absolutely, utterly, meaningless matter in motion or not. Nothing can be "more important" than anything else by definition.
The reason why you have trouble understanding your own primitive, materialistic, philosophy is because we don't live in a purely material, meaningless universe. Such a universe can only exist in a thought experiment, and a very difficult one at that.
