What if the aliens are not from other planets? In THE CRYPTOTERRESTRIALS Mac Tonnies proposes that at least some accounts of alien visitation can be attributed to a humanoid species indigenous to the Earth a sister race that has adapted to our numerical superiority by developing a surprisingly robust technology. At the same time this groundbreaking work attempts to reconcile the mythological and contemporary accounts of little people into a coherent picture. For too long we ve called them aliens assuming that we represent our planet s best and brightest writes Tonnies. Maybe that s exactly what they want us to think.
