Occam's razor cannot be used to assert that when something exists, if must be or indeed is likely, to be in its simplest possible form. Human DNA has plenty of redundant areas and yet we still exist. Indeed, probably all organism have a non-simplest form of DNA and yet still do just fine. We only have one example of a universe and even for that we have an imperfect understanding of its working. It is therefore impossible to know or assert that the universe is it its simplest possible form.
