Los Angeles: Actress Zoe Saldana is convinced about the existence of aliens. The 38-year-old believes that it is logical that there are others in the galaxy, and that there is a place where time does not exist, reports femalefirst.co.uk. "It's so logical to me that there's something else out there. I mean, why would there be so much space otherwise? Plus, I really do believe in a place where time does not exist. I believe there are other Zoes out there and parallel universes and black holes,” Glamour magazine quoted Saldana as saying. "My conscious mind may not have the intellectual capacity to embrace the grandeur of it all, but my being feels it,” added the "Avatar" star.
