10 Alien Species Believed to Be Living On Earth (6 of 6)

10. Sirians

Straight outta Sirius (no, not the satellite radio), the Sirians once allegedly hijacked UK TV in the ’70s to tell us to chill with the nukes. The message was peaceful, which is exactly what you’d say if you were sneakily planning a planetary takeover via unsolicited messages and stone gods. Ancient Egyptians even had a thing for Sirius, so either aliens were guiding civilization or someone got real poetic with their astrology.
