There are many that will say that they are just bird artifacts. However, please show me a bird in nature that has a delta wing and a vertical tail (stabilizer). It is clearly a depiction of an aircraft and theirs is not the only one. Egypt had similar models in their tombs. I guess the Wright brothers were not the first.
