Where there is water, there is a possibility of life
NASA has confirmed that there is liquid water flowing on Mars after searching for 15 years (NASA)
Michael Meyer, lead scientist for Mar's Exploration program said, “It seems that the more we study Mars, the more we learn how life could be supported and where there are resources to support life in the future.” (NASA)
Under the ice-covered surface of Europa, there is a possibility of an ocean of water underneath the cold surface. Due to Jupiter's half a billion miles of distance from the sun, this water is likely to be frozen. However a theory states that the tidal pushing and pulling of Jupiter, as well as its surrounding moons, can generate enough heat to keep the water flowing. (National Geographic)
Life can survive in the harshest of conditions.
Poisonous cave in Mexico - represents cave in Mars.
Lake in Alaska - represents the ice and water in Europa.
Biofilm - community of microbes bound together in a gooey blob. These were found living in the poisonous cave, staying alive by acquiring energy from the toxic hydrogen sulfide. (National Geographic)
No concrete evidence - any evidence there is, however, is very theory based.
No actual sightings nor photos documenting alien life so far. All research done is based on theories.
We are unique, and even if there were life it would be at least more than 1000 light years away and it would be impossible to make contact. (The Telegraph)
The Drake Equation: The variables of the equation are not determined with confidence. They are based on what we already know about the universe and using this knowledge to make assumptions. This makes the result of the Drake Equation inaccurate.
If there are indeed
civilisations like ours, why hasn't one of them made contact? A galaxy of 10 billion planets, some with conditions similar with those of Earth, yet no visits nor communication. (International Business Times)
The Drake Equation, an equation that was created to predict the number of extraterrestrial civilizations with which we might come in contact, proves that the chances not extremely rare and gave people hope.
The Drake Equation
N = R* × fp × ne × fl × fi × fc × L
N = number of ET civilisations we might be able to communicate with.
R = rate of star creation in our galaxy
fp = fraction of those which have planets
ne = average number of planets that can potentially support life per star that has planets
fl = fraction of
which can actually continue to develop life
fc = fraction of
which are willing/able to communicate with Earth
L = expected lifetime of a civilisation like the above
