Humanity has been able to propose many hypothesis on creation of life on our planet. Majority of scientists agree that the origin of life took place millions of years ago, and since then we have been evolving from amoeba to humans. It is this knowledge that compels us to wonder why such a process could not have happened on a place which is not of Earth.
Probability of existence of Aliens
There are nine planets in our solar system, around our “Sun”, a G2V star. Then there are billions of stars in our galaxy. Until recently, we knew the number of stars in a galaxy to be around 100 billion. As on date, the number is proven to be 200 billion. Then we have 10 trillion galaxies in observable universe. If we assume an average of 5 planets around each of these stars, and even 10% of the stars in “habitable zone”, or “goldilocks zone”, we have 1,000,000,000,000,000,000,000,000 planets in our observable universe which could be in Habitable Zone. Do you think that’s a huge number? Yes it is.
Even if we assume there is 0.0000000001% probability of life on any of those Habitable planets, total number of planets favorable to life is a staggering 1,00,000,000,000,000 or around 10 thousand billion planets could have life.
So it means life exists in abundance in our Universe. Not only it is a possibility, it is almost a surety.
Whom do we really call “Aliens”
Any living entity who has originated out of the planet “Earth” is an alien. Whether it is microbes on Europa or a super intelligent species from some other galaxy, each of them are “Aliens”.
To understand who are aliens, watch the following movie, called “Alien Planet – Darwin IV”.
Every living entity shown in this movie is an Alien, whether a monster sucking plant or giant monsters themselves.
Why should we care?
So given the fact that Aliens do exist, should we really care about them? I think we should because of the simple reason that they could be far more advanced and powerful civilization than we are. If they come to know about us, it could be catastrophic for us if they despise us. On the other hand, humanity will do itself a hell lot of good if we can benefit from their technology and civilization. It will be a giant leap for humankind in area of science.
Many believe the contact has already happened some decades ago in Rosewell in United States. Since the event in Rosewell, science on our planet has made great progress, especially in areas of space and defense sectors. It is possible that some countries on earth developed sophisticated technology by virtue of reverse engineering on the crashed spaceship in Rosewell.
When would we encounter Aliens?
According to most renowned cosmologists and physicist, we will encounter an Alien life before the year 2025. That is within 10 years from today. So we are living in quite phenomenal times, as we will be witness to the most extraordinary event in history of human beings. Although the alien life itself could be a microbe or a fungus, yet the importance of the event will lie in getting proof of the fact that life outside of Earth is quite normal, and there are a large number of far advanced civilizations than human beings.
Are Aliens already on Earth?
There are evidences to show that humans are Aliens. It means that we are not a result of evolution of life. Some external life has sown seeds of intelligent life on Earth. Read some more of this interesting concept here. There are also reports of Alien sightings here on earth itself, where people have seen advanced civilizations interacting with humans in limited capacity. Some image grabs from those incidents, which I believe are very credible, are given below.
So, do you think aliens Exist? How do you think we should interact if we come across Aliens? Please express your views in comment section.
