One of my favorite movies is Contact this quote about other life in the universe. “If we’re alone in the universe, that’s an awful lot of wasted space.” So yes I believe there is other intelligent life in distant galaxies, sometimes I question the intelligence of the life on our planet. haha 😛 I do not feel we have anything to fear from other life forms from distant galaxies. I would hope we would deal peacefully with any aliens that came to visit.
