Provide one level then. The most basic forms of primitive communication that express reality would be survival based like 'don't go in that jungle a demon panther lives there', or 'the season is changing, stock food', or telling the history of the village which may or may not be true and still improve the survival chances of offspring. I will concede only that White men living in harsh environments over time will have developed more concepts and words for truth, planning, and logic than jungle tribes.
