Life on earth originated around 3.6 billion years ago as soon
as laws of physics allowed it to happen. In other terms, due to the conditions
present on the early earth, the primordial single-celled organism has risen out
due to complex chemistry.
Life on earth up to 1/2 a billion years ago was present in
single celled state happily doing it's thing like photosynthesizing the energy
from the sun and doing just fine. But suddenly life took a leap by transforming
itself from single celled to multi celled organism.
The complex chemistry became more and more complex as
finally a species named homo-sapiens have arrived into the scene and conquered
the entire planet.
We are the result of continuous transformation through a
continuous process of evolution, and the final product until now is us.
We are so technologically advanced that we made the
electrons our bidding through our whim of hand and doing so many things like
inventing smart phones, inventing internet which our ancestors thought as
sorcery. And we did escape our clutches of gravity and went to the moon, which
is the first step of technological civilization because if two alien
civilizations need to contact each other, firstly they need to learn to escape
their host planet's gravity.
So, back to the aliens, the observable universe consists of
2 trillion galaxies , each galaxy with 100 billion stars, which together puts
up to 1 sextillion stars.
In this vast and immense scale of the cosmos, extremely
complex chemistry arise on at least one planet known as earth orbiting an
insignificant star namely sun.
The life is mostly made of hydrogen, oxygen, nitrogen,
carbon and other elements. The universe in order consists of exact same
elements in exact same way. We are one-on-one matching with the universe. How
ever complex life may be, the universe created it from simple elements.
So in 1 sixtillion stars, do you think that we are alone in
the universe? if so it is huborous on our side to think so. The universe is so
vast and spaced out that we didn't find any evidence of alien species, that
doesn't mean there are none considering the immensity of the universe.
If, for example our life is made of isotope of bismuth or
other higher elements, then we can say that there is something going on down
here, but it's not.
So however it may be, it is ridiculous on our part to say
that we are alone in the universe.
So, if you want to meet alien civilization, then you go to
their planet than they coming for us because if we go to that planet, we are
superior than them and vice versa
The difference between a rock and you is the complex
arrangement of atoms and nothing else. In this 13.8 billion years timescale we
may not be able to possess more complex chemistry at our disposal than now, so
be grateful that universe exists and you too after the grueling competition you
have gone through like participating in races, competitions before rewarding
yourself with brimming life.
So probably aliens do exist, we just didn't found them out 👽
