Idea - How original is it?

So many debates have taken place discussing on the very concept of idea and how original it is.

Technically speaking, you as being a human on this planet, it is impossible to come up with an idea which can be called original, as whatever you think are limited to your human experiences and hence your thought as unique as it might be would have already been thought or will be thought by someone else for surely. So an idea becomes really an offshoot of an idea of an idea of an idea.

So then is it really possible for an idea to originate which can be unique – Yes. The answer is simple, if an extra-terrestrial/ alien (Not to be confused with ET) with an intelligence level which is at par or exceeding humans, visits us and thinks of an idea…Then that can be technically called as being original.
