Shane Warne has proposed a strange theory about where humans came from.

Currently participating in the reality show 'I'm a Celebrity Get Me Out of Here', Warne told a fellow contestant that "we started from aliens.”

Speaking to dancer Bonnie Lythgoe, he said: "If we've evolved from monkeys, then why haven't those ones evolved?"

He added: "Because, I'm saying, aliens. We started from aliens."

Lounging in South Africa's Kruger national park, the former Australian cricketer explained his theory by saying: "look at those pyramids, Bonnie. You couldn't do them. You couldn't pull those ropes, huge bits of brick and make it perfectly symmetrical. You couldn't do it. So who did it?"
