And you cannot prove that the Ica Stones are authentic. However, the vast majority of the evidence about the Ica Stones suggests that the Ica Stones are a hoax.
1. The Ica Stones depict man riding dinosaurs when there is no other evidence of man and dinosaur living together. Furthermore, there are no dinosaur bones and human bones that have been dated to the same time period.
2. The Ica Stones depict man using telescopes to look at the stars. Is it your view that man thousands or millions of years ago developed optics and and the technology to build telescopes?
3. The Ica Stones depict man riding horses when there is no evidence whatsoever that horses existed in the New World in pre-Colombian times.
4. The Ica Stones depict humans performing open heart surgery and brain transplants thousands of years prior to the ability to conduct hear surgery.
5. Javier Cabrera who bought the Ica Stones from locals and claimed to know the original source of the stones never revealed that original source.
6. Basilio Uchuya who sold the Ica Stones to Cabrera admits that he and his wife carved the Ica Stones!

Care to prove that the stones are authentic and man and dinosaur did live together while people gazed at the stars with telescopes, received open heart surgery and brain transplants all while riding around on dinosaurs?
Messing with you isn't right either, but I'm not perfect.
