Does originality exist?

In my opinion, originality can be classed as a new concept or a new theory that has never been seen or explored before, but it then depends on what you are applying the term "originality" to and how loosely you apply it - if you question the originality of a design concept, you must question the influence the design has had and why the designer has chosen that design. If you look at the history of a product or design, you can more often than not trace its roots to the first time the product was invented and built, which you could then argue is the original concept, but if you were to look at the very first design you should look at the influence the designer took from their own experiences. I feel originality can only exist through influence- but does this mean originality doesn't exist at all.......?
