Some people think that there is nothing new under the sun, the book of Ecclesiastes also states this, this is the basic idea, there is nothing new, everything changes, and the old information/knowledge, is reformatted to some other type. We can see this in books that we read, Harry potter is a good example, all the creatures in these books, the characteristics of the main characters, and even the writing style is much like …showed first 75 words of 517 total…

…showed last 75 words of 517 total…that thing different, thus, if you took someone elses writing, and added another persons plot, and added a main character from a different story, then you would have a story that is new, you brain had the same information compiled differently in it. It added it to the story in its own way, and created something unique. This is something that happens all over the place, thus, there really is nothing new under the sun.
