Have you ever wondered if aliens are real? Scientists have been looking into this question for a long time. They want to know if life exists on other planets. The Fermi Paradox is a theory that tries to explain why, even though there are so many planets, we haven’t found aliens yet.
- What is extraterrestrial life: It means life that exists outside of Earth, possibly on other planets.
- Why we haven’t found aliens yet: The Fermi Paradox asks why we haven’t seen any signs of aliens even though space is so big.
- Scientists search for life: Scientists use telescopes and other tools to look for signs of life on other planets.
- Many planets could have life: There are billions of stars and planets, and some might be able to support life.
- Still a mystery: We haven’t found proof of aliens, but scientists continue to explore space for answers.
