I mean, this is only an idea, but there's a possibility that the Mayans were trying to change the timeline. It seems to me the possibility that sometime in our future that on a certain timeline that mankind is destroyed or nearly completely annihilated and is then replanted on the earth. If this scenario is correct, then essentially what we're doing is we're living in the past and some of these cultures were aware of this knowledge and what they were trying to do was try to almost avert a catastrophe. by completely changing what the timeline would be in terms of the next generation and the next population.
