Do Alien Lifeforms Exist? Maybe, But We Can't Communicate With Them

Is the Earth the only planet with life forms in the universe, or are there many alien civilizations that we've never heard of? The concept of being alone in the entire cosmos is scary, but having other living civilizations alive without our knowing, equally so.

There are many questions regarding the existence of alien life-forms -- if they are there, can they communicate with us on earth? An answer took place in 1961, when Frank Drake, and astronomer proposed what is now known as the Drake Equation.

Still, even with the equation drafted, questions about alien life forms are not easy to answer, and despite what we see on "Star Wars", "Star Trek," "Doctor Who" or any other sci-fi hit. However, a new paper in Astrobiology suggested that life is plentiful in exoplanets, but they are likely all extinct.

Lead researcher Adam Frank said in a statement as printed by Disovery that scentists have known long ago how many stars exist, but they didn't know how many have planets, could harbor life, or even intelligent beings.

However, there are elements that Frank and his co-author, Woodruff Sullivan think could be changed.

Discovery outlined the three elements, being the number of stars with habiabel planets, the survival rate of such civilizations, and the likelihood of advanced life to arise on a planet.

The authors dubbed their result as the "archaeological form" of the Drake Equation. However, the likelihood of the existence of technological species is incredibly low -- there is a one in 10 billion trillion chance that humanity is alone. However, the certainty of how long these civilizations could exist indicate that it may not be possible us to communicate with any of them out there, and vice versa.
