Baker in “The Aliens Among Us: Hypnotic Regression Revisited”, The Skeptical Inquirer, 1988

Why Explore Space? Colonization - Marvin the Martian wants to colonize Earth and We want to colonize Mars Science - We want to understand the universe and other planets Communications - Every day we use hundreds of satellites to communicate with other Earthlings Weather and Navigation, and the list goes on Colonization - Marvin the Martian wants to colonize Earth and We want to colonize Mars Science - We want to understand the universe and other planets Communications - Every day we use hundreds of satellites to communicate with other Earthlings Weather and Navigation, and the list goes on
