The Visitor

In an enigmatic, alien landscape, Jerzy Colsowicz (John Huston) experiences a vision of a powerful and destructive storm brought about a young human girl. His colleague, an enigmatic Christ-like figure (Franco Nero), tells his bald pupils about the centuries-long cosmic conflict between Zatteen, an evil inter-spatial force of immense magnitude with powerful psychic abilities, and his benevolent arch-rival Yahweh. Zatteen escaped to the planet Earth centuries ago, and though he was eventually tracked down and killed by Yahweh, his spirit lives on in the minds of Human, waiting for an opportunity to reemerge and wreak havoc. The figure tells his disciples that before his death, Zatteen had produced dozens of children with human women, and these descendants continue to populate the Earth.
