Impressive Alien Carving Discovered on Spanish Cathedral - Video

Very impressive carving that seems to depict an Astronaut holding a tether of some kind. The carving is part of a decorative mosaic of motifs, that decorate the Ieronimus Cathedral in Spain.

De-bunkers have claimed that this is merely the work of a mischievous builder who worked on the restoration of the cathedral back in 1992, but some local sources reject that theory claiming, the people who have lived here for generations all know about the hombre de las estrellas, (Man Of Stars) Our grandfathers and grandmothers all talked about him, its common knowledge.

Could this be proof of Time Travel, Alien visitation?
