According to a presentation by Cody Lawrence, while most people believe intelligent life exists elsewhere and we should search for it, actively searching for and contacting extraterrestrial intelligence may endanger humanity. The SETI program uses telescopes and radio signals to search for life, but contacting aliens could lead to communication problems or reveal to others our planet's resources, potentially attracting hostility. Given human conflicts on Earth, coexisting peacefully with aliens may not be possible.
