In a homily delivered Monday, Pope Francis said he'd totally baptize Martians if they showed up at the Vatican demanding to be baptized.
He was trying to illustrate the point that everyone has the right to receive the Holy Spirit -- even aliens from faraway planets.
" If tomorrow, for example, an expedition of Martians arrives and some of them come to us ... and if one of them says: 'Me, I want to be baptized!', what would happen?" the pontiff said, according to AFP.
He defined these hypothetical beings as "green men, with a long nose and big ears, like children draw." For extra emphasis, he added, "Who are we to close doors?"
