For us, the Earth is vast and home to more than 8 billion people, but on the scale of the universe, the Blue Planet is very small.

To better understand the vastness of the universe, let’s imagine that the Earth is located in the Solar System of the Milky Way galaxy and in the universe there are trillions of different galaxies.

The galaxy containing our Earth alone has about 400 billion stars.

If the Milky Way galaxy is the size of Vietnam, then for the Solar System containing the Earth, it is less than half the size of a coin and until now, humans have not been able to fully explore the galaxy where they live.

This has prompted a group of scientists around the world to believe that in the trillions of galaxies of the universe, there will also be other civilizations.

In the past, many space observatories of international astronomical organizations continuously received strange signals, making many scientists believe that aliens may have visited or are sending greetings to humans.

Some astronomers have even published their research concluding that extraterrestrials are watching and want to live with us.

The story of the appearance of an extraterrestrial civilization or that they have visited us has always been a fascinating and controversial topic in the scientific community.

Area 51 is known by some as the place where aliens live on Earth, it is located separately in the Nevada desert (USA), and the road leading here is even named “Extraterrestrial Highway”.

For those who know this mysterious road, it leads to a US military base with many unofficial names such as Paradise Ranch, Water Street, Dreamland Tourist Area, Division 3 and especially the name Area 51.

Notably, the road is not marked on the map, making it even more attractive to alien-related speculations.
