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."
