you do know people can learn any number of different languages right?
also it has happened before that native culture lose their native language and traditions due the actions of the colonizers and governments.
I am surprise that the legend of the bird human and the influence of the Protoculture was still present in the Mayans. For Protoculture legend and influence to still exist in the Mayan it should have been introduced within the last couple thousand years for it to survive word of mouth like within the last 10,000 years. It is stated that the Protoculture initiated the evolution of humanity so if they trigger it from our most ancient ancestors would that be what, 8 million years ago? if they triggered the evolution of modern humans that would have been when around 200,000 years ago?
Was there a age for the Aphos remains stated in M0?
I always thought that Deculture meant incredible, impossible or some statement of amazement. Considering that homo sapiens means "thinking man" and the meaning of human is "to be kind and gentle" would it be impossible to think that Protoculture meant "the amazing people" ?
