The creative power (god) has taken shape the way we are shaped. The most imperative venture is to preserve this gift of life elsewhere should something go wrong—keeping us in play should cataclysm strike.
Whatever the case, space travel is a way to save god—to insure that life, awareness, and perception in the universe live on forever.
“The theologians have myths, the scientists have theories—and both ends in mystery and ignorance”, Ray Bradbury
Either way space travel is an insurance policy of continuity—to insure that human life continues unbroken. To save god in its current image is our only legacy. Can we pull it off in time to beat the day of doom?
