Portrait of aliens under the perspective of scientists

Since ancient times, aliens have always been a mystery to scientists. Do they really exist? And what if they really look like? Here are some sketches that collect the most common features of alien appearance from the perspective of scientists.

According to scientists, aliens live on the ground to develop ballistic missile technology. They have eyesight as if they were attached with binoculars, making it possible to observe from a distance.

Aliens look superficially similar to us.

Their eyes must be close to the brain to minimize the time between the time of receiving data and processing signals. Aliens have at least two legs to operate and the hand must consist of at least 3 fingers to grasp and use certain objects and tools.

With these characteristics, aliens look superficially similar to ours.

According to Richard Dawkins - a world leading expert on evolutionary theory, it is not surprising. Mr. Dawkins said macromolecules like proteins or DNA are the same everywhere. If that really happened, then all life on this universe would grow like the Earth, maybe even create 'people' that could walk and talk like we do.

However, not everyone agrees with that idea. Expert Neil Degrasse Tyson - an American astrophysicist who is the director of Hayden Planetarium (New York) - says aliens can form from some human-like chemicals like helium gas. , carbon, oxygen . but that doesn't mean their looks have to be like us.
