The zookeepers are having fun as earthlings are trying to stack the boxes - What do you think about the zoo hypothesis?

Where is everybody? The zoo hypothesis is one of a number of suggestions that have been advanced in response to the Fermi paradox, regarding the apparent absence of evidence in support of the existence of advanced extraterrestrial life. According to this hypothesis, aliens would generally avoid making their presence known to humanity, or avoid exerting an influence on human development, somewhat akin to zookeepers observing animals in a zoo. Adherents of the hypothesis consider that Earth and humans are being secretly surveyed using equipment located on Earth or elsewhere in the solar system which relays information back to the observers. It is also suggested that overt contact will eventually be made with humanity once humans reach a certain level of development.
