Humans are trying hard to find any space life in the universe and so far no success has been achieved. However, US scientists have claimed that aliens are already living on Earth.
This claim was made by Harvard University experts in a research paper in which it was said that it is possible that aliens found in other worlds are living under the surface of the Earth or the Moon, while flying saucers or unidentified aerial phenomena (UAPs) are evidence of it.
The research also explained about unidentified aerial phenomena which has not been identified yet. The term is used for aerial objects that have not been identified and are believed by many to be flying saucers.
The Harvard experts used the word anomalous instead of aerial for the UAPKA, saying that some types of UAPs may travel underwater.
According to the researchers, it is possible that UAPs are quietly living on Earth (under the surface) or near us (the Moon) or walking around with us (in human form).
They described 4 theories regarding the presence of aliens with humans.
