Do aliens exist?

From the start of human advanced civilization and technology, we have been wondering: “Is there anyone or anything with intelligence? If yes, how will they look like?”

Nasa has set up a centre called SETI (Search for Extra-Terrestrial Intelligence) to listen for radio, electromagnetic and patterns in stars that might correspond with aliens. Back in the early days of technology, the professors at Cambridge University discovered what might be an alien transmission. It was named LGM-1 (Little Green Man due to the notion that aliens were short, green people)

Later, this was confirmed to be a neutron star, a dense star core that rotates and gives off waves that the astronomers detected. Many people believe the government is covering up after the Roswell Incident, which the US claims to be a weather balloon, but many speculate this is a makeshift UFO, it is still unconfirmed to this day.

The chance of we having aliens is high, considering the universe has 10 to the power of 22 stars, each in a system with several planets, one in five has an Earth-like planet.

Then comes the Drake Equation :

N = R* • fp • ne • fl • fi • fc • L 

Where N is the number of ETs in the universe, R is star formation rate that is suitable for life, fp is stars with planet system, ne is he number of planets, per solar system, with an environment for life, fl is the planet that actually have life, fi The fraction of life bearing planets on which intelligent life emerges, fc the fraction of civilizations that develop a technology that releases detectable signs of their existence, L is the length of time they release the signals into space.

If so, the N number is huge and more than 1 million will be found.

The possibility is huge, but there are yet to be discovered.
