Do aliens really exist? - PAU Madrid 2015Alien” is a word used to refer to beings from other worlds. Do aliens exist on Earth? No one knows the answer for sure, but it is a question that has been debated for ages. If history is to be believed, aliens have been a subject of mysticism in civilizations of places such as India, China, Babylon, South America and Arabia. The external appearance of aliens is also a much discussed matter: they have been depicted as green monsters, small creatures with arms and legs like humans, tiny viruses or beings that change appearance at will.
Many people nowadays, including well-known scientists such as Carl Sagan or Frank Drake, are tireless propagators of the theory that aliens are in fact regular visitors to Earth. This theory is supported by many reported alien sightings. For example, a person waiting at St Martin airport claimed to see fire in the sky; the fire suddenly transformed into a silver ball, moved over him like a jet and vanished in a few seconds. And two brothers in Chile said that they saw a humanoid creature about 80 cm tall, shiny and red, who resembled a child wearing a driver’s suit. 
However, others believe that aliens are just figments of imagination. This view also has scientists on its side, such as Enrico Fermi. He proposed the famous “Fermi paradox”, which states that there is an apparent contradiction between the strong belief in the existence of extraterrestrial civilizations and the present lack of solid evidence for, or contact with, such civilizations.
Putting the two views together, we cannot be sure if aliens are real unless and until we have strong evidence about their existence.
