Any origin story makes more sense than "just because", that's why they exist in the first place : to make sense of what happens in the story. It's not mandatory off course, sometimes you just don't care and even don't want to to know to preserve the sense of wonder, but an explanation will always make more sense than none, especially if the writer worked on it to make it more believable.
