4th PIECE OF EVIDENCE THAT SUGGESTS INTELLIGENT ALIEN LIFE EXSISTS

THE DARK EQUATION:

N = the number of civilizations in our galaxy with which communication might be possible;
R* = the average rate of star formation per year in our galaxy
ƒp = the fraction of those stars that have planets
ne = the average number of planets that can potentially support life per star that has planets
ƒℓ = the fraction of the above that actually go on to develop life at some point
fi = the fraction of the above that actually go on to develop intelligent life
ƒc = the fraction of civilizations that develop a technology that releases detectable signs of their existence into space
L = the length of time such civilizations release detectable signals into space.

Radio astronomer Frank Drake developed the Drake equation so he could estimate the number of planets harboring intelligent life in the galaxy by taking into consideration the factors listed above. A rigorous estimate using the Drake Equation was implemented in 2001, which also took into consideration the number of planets that are in the habitable zone (The habitable zone is an area around a star were water is in liquid form, temperature is ideal, and photosynthesis is possible). The results found that hundreds of thousands of life-bearing planets statistically should exist. It also suggested that a habitable planet like the Earth should exist just a few hundred light years away.

I find it unfair if I did not now also give equal mention to the Fermi paradox. The Fermi paradox states that if so many planets exist with intelligent life why is there a lack of contact between the intelligent life and us and why is there such a lack of physical evidence of said intelligent life. The paradox exists in that the Drake equation statistically proves life should be abundant and yet physical evidence says otherwise. It is hard to combat the arguments from the Fermi paradox except that some physical evidence does exist as you can see from this writing.
