It seems to me that what Randall Carlson and Bright Insight have done here is to assume that scientific findings in connection with ancient constructions are sufficient justification to attribute intentional design to the original builders – whether ancient Egyptian pyramids, or constructions in the New World (as exemplified
here).
If ancient builders did have such knowledge, and designed constructions with such purposes in mind, that’s fine: but cultural evidence would have to be found to support such a theory. Simply discovering electromagnetic properties, or achaeoacoustic phenomena, is not enough in itself. This is what people like Randall Carlson and channels like Bright Insight don’t seem to understand.
