Do Aliens Exist?Theories,Evidence and Mysteries of Extraterrestial Life

 Introduction:

Have you ever thought about Aliens?In this world,there is lot of galaxies,planets are there.You have to believe in aliens because there is so much of possibility to have atleast one group of alien civilization in our universe.Some planets(Keplar)are like our earth is there.Keplar is the planet which is like earth,it is also called as Earth 2.0,as they are in the habitable zone.So,scientists are claiming that there might be water,oxygen and carbon.These three components is essential for existing of a life form.Scientists claiming that aliens are made up of Silicon and they will have a large or oblong face with large eyes.Many scientists are 100% sure of existence of an alien civilization.We tried so much time by making a signal sent to the universe and that signal is travelling till now and it will travel until the universe ends.But,still there is no reply from any Alien civilization.By this we cannot make a judgement that alien is not there,may be they lack in technology,so they can't received our message or they have technology might they got the signal,but they may taught to don't reply for our message.Some of the scientists claiming that alien civilization will have advance technology than our human made technology.

Let's deep dive into this Legend!!

Some theories about Existence of Alien civilization:

1)The Roswell UFO Crash Theory:

One of the most famous alien theories is the Roswell UFO incident.In 1947,a mysterious object crashed at Roswell,New York.The U.S military said that it is a weather balloon,but conspiracy theorists claimed that it is an alien spacecraft.

Mystery:

Some people claims that the government secretly recovered alien bodies and took them to area 51 for research.

2)Area 51 Alien Technology Theory:

Area 51 is a highly classified U.S Air force base in Nevada.

Theory:

People believe scientists there study alien technology,UFOs and possibly even living extraterrestials.

Reality:

The U.S government confirmed Area 51 exists in 2013 but said it is used for testing experimental aircrafts.

3)Ancient Alien Theory:

This theory suggests that aliens already visited our earth and helped our ancient civilizations for betterment of the ancient people.This theory also adds more point to some wonders of our world.

Supporters point to mysteries like:

>>>Nazca lines

>>>Great Pyramid of Giza

>>>Stonehenge

The conspiracy theorists believe that our ancient people have a connection with alien civilization and they helped our ancestors to build these kind of wonders of our world.They claims that without advance technology,we cannot able to build Great Pyramid of Giza,the Nazca lines and stone henge.Because,the the pyramid present in giza has so many limestones and one limestone has a weight ranges from 2.5 to 15 tons.So,how our ancestors take the stones and built the pyramid in that pyramid at that period,even now with our modern technology we can't easily do this.

Nazca Lines:

The Nazca lines are enormous drawings created on the desert ground is Nazca desert.These lines from shapes of animals,plants and geometric patterns.They were made by the ancient Nazca civilization between 500 BCE and 500 CE.

What makes them mysterious is that the designs are so large that they can only be clearly seen from high in the sky.Because of this,some alien theories believe the lines were created as signals or landing markers for extraterrestrial visitors or aliens.However,most archaeologists believe the Nazca people created them for religious and ceremonial purposes.

Great pyramid of Giza:

The great pyramid of giza,located in giza,is one of the most famous structures in the world.It was built more than 4500 years ago during the reign of the Egyptian pharoah Khufu.

Because of the pyramid's massive size and the precise way the stones were arranged,some people think ancient humans could not have built this wonder without advanced technology.This has led to theories that aliens may have helped design or construct the pyramid.

However,historians and archaelogists have found strong evidence that ancient Egyptians built the  pyramid using human labour,engineering skills and simple tools.

Stonehenge:

Another mysterious ancient structure is Stonehenge,located in Wiltshire.Stonehenge consists of massive standing stones arranged on a circular pattern and it is believed to be over 4000 years old.

Because,the stones are extremely heavy and were transported from far away,some people speculate that aliens may have helped move or place them.Others believe that Stonehenge was used as an astronomical calendar to track the movement of the sun and the seasons.

Scientists today believe that ancient people built the Stonehenge using teamwork,basic tools and clever engineering techniques.

UFO Sightings around the world:

Thousands of people report seeing UFO every year.Many of these sightings are turn out to be:

1)Weather balloons

2)Military aircraft

3)Satellites

4)Natural Atmospheric Phenomena

In recent years the united states department of defense has acknowledged some sightings of UAP(Unidentified Aerial Phenomena) that remain unexplained does not necessarily mean alien.

The Fermi Paradox:

Scientists also discuss the Fermi Paradox

It Discuss:

If alien civilizations are common in the universe,why haven't we found clear evidence yet?

Possible Explanations include:

1)Intelligent life is extremely rare

2)Civilizations destroy themselves before space travel

3)Aliens are too far away

4)They intentionally avoid contacting us

Conclusion:

Alien life might exist somewhere in the universe because space is unimaginably large.However,events like Rosewell crash and Area 51 remain unproven theories and mysterious,not confirmed facts.Scientists continue searching for answers and future discoveries may finally reveal whether humanity is truely alone in the universe.

My Opinion:

In this universe,there is lot of galaxies like Andromeda,Milkyway and some Spiral Galaxies are there.So,in this big universe we are not alone and we are in the habitable zone like keplar B planet.In keplar B,Scientists claiming that there is a chance of existence of water and atmosphere like our Earth and they also said that there might be living organism(Alien) in an aquatic form or land form.So,in this universe we are just like a point according to our universe.So,I am 100% sure about the existence of alien is true!!
