NASA Expert: No Aliens on Earth, But Life Exists Elsewhere!
25 Feb
Summary
- No alien machines or beings have ever landed on Earth, says NASA expert.
- The universe is overwhelmingly likely to host extraterrestrial life.
- Earth-like planets like TRAPPIST-1e and K2-18b are prime candidates for life.
Dr. Gentry Lee, a NASA veteran since 1968, stated at a conference that there is no evidence of alien visitation to Earth. He believes simpler explanations exist for UFO sightings, countering claims of extraterrestrial encounters. Despite this, Dr. Lee is confident that life exists elsewhere in the universe due to the vast number of planets discovered. He noted that space telescopes like Kepler have identified nearly a trillion planets in the Milky Way galaxy alone, making the odds of life forming elsewhere overwhelming.
Scientists are focusing on 'Earth-like' exoplanets, including TRAPPIST-1e, located 40 light-years away, and the 'Hycean world' K2-18b, 124 light-years distant. Even moons in our solar system, like Enceladus and Titan, are considered potential abodes for life. Dr. Lee also emphasized that alien life might be fundamentally different from Earth's DNA-based organisms.
