Answer 2

$\huge \mathfrak {ANSWER :-}$

UNIVERSE is a Vast Region which is Expanding At a Rate which is Faster then Light.【SETI】 has been Sending Radio Space into The Outer Space For Decades and We've Heard back from From Exactly Zero.So, The Big Question,"WHERE ARE EVERYBODY".

The FERMI PARADOX comes into Play in this Situation which is a Apparent Contradiction between the Lack of Evidence and high Probabilities of Estimates regarding to the Existence of the Extra Terrestrial Life.

For the Fact, The Milky Way Galaxy Has around 400 billion Stars. For every Grain of Sand on Earth there is 10000 Stars Up in the Sky.Using this Numbers, We Can Find that There Should be atleast 100,000 to 1 Million Earth like Planets in The Milky Way Alone where Life Could Develop.

Hence, It would not be fair to say that Earth is the Only place where Intelligent Life Has Developed.Maybe there Could Be Some Other Civilizations who know where we are but are Not Responding To our signals.

The Thing Is There Are Millions Of Earth like Planets in the Universe but We can't be Sure that there Is Some Life out there.
