Question

Do Aliens Really Exist?

“Alien” 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.

Answer 1

Question 5:

We live in a Universe that has millions of galaxies, of which we know almost nothing, given this simple premise it’s not hard to think that there may be more intelligent being apart from human beings.

Though almost everyone you told that you believed in aliens would call you crazy, there are facts that can support your thesis. Many evidences speak for themselves when it comes to explain why it could be possible that we had been visited by aliens at some time of the world existence. Some experts believe that it is almost impossible to build structures such as Egypt’s Pyramids even with the technology we have nowadays! There are some other facts that could be explained by those visit, for instance, common patterns between cultures of Asia and America that would be quite hard to explain if we don’t link them to UFOs.

The obvious point of view on aliens is that they don’t exist, they didn’t visit us and all those strange things so hard to explain are just coincidences, the question is: are they actually coincidences?
