Scientists have revived one of the most intriguing ideas in the search for extraterrestrial life: the Zoo Hypothesis. This theory suggests that advanced alien civilisations could be observing humanity from afar using technology so advanced it remains completely invisible to us. Much like humans watching animals in protected reserves, these civilisations might monitor Earth without interfering, choosing to remain hidden while studying our development. The idea emerged as a possible solution to the Fermi Paradox, which asks why a universe full of potentially habitable planets appears silent. If the Zoo Hypothesis is true, the silence may not mean we are alone it may mean we are being watched. https://collective-spark.xyz/meti-scientists-earth-could-be-galactic-zoo-run-by-aliens-luis-elizondo-embraces-zoo-hypothesis/
