I was watching ancient aliens ( yes that crazy show) and I put 2 and 2 together and well I think I know what puma punks was used for. I studied the sciences to university level in the UK and this idea used facts we know to be true and could prove that aliens came to planet earth. I have emailed the history channel but I fear I will be ignored. There are authors on the show who may be interested but will they steal my work?
