A leading biological anthropologist has proposed that the mysterious beings behind countless UFO sightings could be time-travelling humans from Earth's future, returning to monitor their ancestors as the planet faces potential environmental catastrophe. Dr Michael P. Masters, professor of biological anthropology at Montana Tech University, has developed the Future Human Theory.
It posits that what we call aliens are in fact our descendants from a future Earth, equipped with technology to travel back in time. Rather than extraterrestrials from distant planets, the classic 'greys' described in abduction reports are humans from a future Earth, possibly one threatened by climate change or other self-inflicted crises.
