Yes we have visitors, but a more mundane explanation is possible: we share our planet with an ancient civilization. Quite right Ed, However that 'correct' assumption rests only on current knowledge of Relativity and QM. Several scientists (and am just now re-reading Penrose's 'Emperor's New Mind' where he seriously considers it), are looking at matter transmission and even transmission of a person - complete with 'consciousness' - by way of entanglement. The minimum speed of such a tranfer would be light-speed, and sometime in our future (but maybe other folks' present?) we might find the secret of that 'instantaneous force over arbitrary distance' which shows up in QM experiments.
