Since no-one could write this a work of hearsay and fiction. The only records existing come from when Europeans arrived.

wall of excrement probably lol

Nice fairy story, BUT, abiogenesis (life emerging from non-life), is proving to be IMPOSSIBLE, the more we learn. 1.- Complex proteins break down in just HOURS outside the cell. Deep time is the ENEMY of trying to create life in a lab. 2.- DNA information, cannot be added through mutations. The vast majority of mutations DELETES information, making DNA strands smaller and simpler resulting in net loss over time. 3.- DNA bottle-necks result in apparent diversity, but these are in reality the LOSS of DNA DIVERSITY and information. For example genetic problems in dog breeds. 3.- Natural selection is similarly the DELETION of diversity from the genome. 4.- The complexity of DNA structure, where proteins fit in 3D and change their own structure depending on environmental conditions, points to a very sophisticated INTELLIGENCE.
