Yupp, that would mean more or less all invention is based on alien technology... :D

I'm thinking they probably would have invented the wheel, and probably have used it as we did to build a cart ect...

I think I badly worded my title.  What I meant to ask was what might they have invented that we would we instantly recognise as something we also invented on earth.

I would recomend taking a closer look at the Dogon creation story, especially the Nommo, fish-people who came to earth from sirius B, which in the myth is described as being of a material denser than lead and the companion of another, presumably sirius A

If aliens exist, what things might they have invented that we would recognise on Earth?
