Alien Design
One hypothesis is that the Universe may have been designed by extra-universal aliens. Some believe this would solve the problem of how a designer or design team capable of fine-tuning the Universe could come to exist. Cosmologist Alan Guth believes humans will in time be able to generate new universes. By implication previous intelligent entities may have generated our Universe. This idea leads to the possibility that the extraterrestrial designer/designers are themselves the product of an evolutionary process in their own universe, which must therefore itself be able to sustain life. However it also raises the question of where this universe came from, leading to an infinite regress.
The Simulation hypothesis promoted by Nick Bostrom and others suggests that our Universe may be a computer simulation by aliens.
The Biocosm hypothesis and the Meduso-anthropic principle both suggest that natural selection has made the universe biophilic. The Universe enables intelligence because intelligent entities later create new biophilic universes. This is different from the suggestion above that aliens from a universe that is less-finely tuned than ours made our Universe finely tuned.
The Designer Universe theory of John Gribbin suggests that the Universe could have been made deliberately by a member or members of a technologically advanced civilization in another part of the Multiverse, and that this advanced civilization may have been responsible for causing the Big Bang.

Famous quotes containing the words alien and/or design:
“Every one of my friends had a bad day somewhere in her history she wished she could forget but couldn’t. A very bad mother day changes you forever. Those were the hardest stories to tell. . . . “I could still see the red imprint of his little bum when I changed his diaper that night. I stared at my hand, as if they were alien parts of myself . . . as if they had betrayed me. From that day on, I never hit him again.””
—Mary Kay Blakely (20th century)
“A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering.”
—Freeman Dyson (b. 1923)
