Not really. It reminds me of the way all major early cultures built pyramid-like structures in similar manners. If there is a connection, then it must be something like aliens since we also find these pyramids with pre-columbian cultures.

But the explanation is much simpler: the pyramid shape is just the easiest way to stack stones! It is the most basic application of one of the most important principles when building tall structures: the higher you build, the wider your base needs to be compared to the top.

This might be something similar: two "cultures" arriving at the same shape independently because it derives naturally from their premises.
