There are not even two things exactly the same, as far as I can tell.
That is a common definition of identity, two things are the same if all their properties are the same. So by definition there can not be two different things with all their properties the same as this would make them indistinguishable and therefore the same thing. But if you relax this a bit, then for example elementary particles like electrons are - as far as we know - all completely identical up to their position, momentum and spin.
