Scientists simulated a galaxy similar to our own and allowed solar systems to develop based on known exoplanets. Over 700 exoplanets have been identified in over 600 planetary systems. Life on other planets could exist in many forms, just as on Earth, and intelligent life may look or behave differently than what we expect. While life is difficult to form, it evolves easily. Some scientists estimate hundreds of intelligent civilizations could exist in our galaxy alone. Prokaryotes like bacteria and archaea would likely be the first lifeforms to develop on other planets where life emerges. Some believe aliens may already be observing Earth and have provided technologies, though this is denied by governments and scientists. Advanced alien civilizations could be more developed than

1. The life out of earth
Created by natia koiava

2. Scientists simulated a galaxy much like our
own, allowing it to develop solar systems based
on what is now known from the existence of so-
called exoplanets in our galactic
neighborhood.

3. We have identified 760
exoplanets in 609 planetary
systems and 100 multiple
planetary systems

4. If aliens really exist,
what form they take?
Life on other planets
may be as varied as
life on Earth and we
cannot predict what
intelligent life on
other planets would
look like or how they
might behave.

5. Variety of life on
earth

10. It is difficult for life to be formed but easy
for it to evolve
Scientists suggested there were 361
intelligent civilizations in the galaxy

11. life was easily
formed but
struggled to
develop
intelligence. Under
these conditions,
31,513 other forms
of life were
estimated to exist.

12. life could be passed
from one planet to
another during
asteroid collisions –
a popular theory
for how life arose
here on Earth.

14. From all the life we know, prokaryotes (archea and
bacteria) are the most widespread organisms, in
time and space. They are the first organisms that
populated the Earth, and would likely be the first
dwellers on other planets where life may have
developed.

15. Other group of
astrobiologists
claim that aliens
already know
about us .and
that they are
observing our
planet.

16. ’’It's a fact that aliens have been
visiting Earth for last several thousand
years. Many of our technologies are
gifts from them. It is a different matter
that our Governments and some our
scientists are in constant denial.
Maybe this is their policy or perhaps
the aliens have asked them to keep
their identity secret in lieu of technical
inputs given.’’
Shailendra Singh, Mumbai

17. Are they more developed then we?
Probably some of them really are,
because some may be the older forms of
life then we.

18. So imagine that, tomorrow morning you’ll see their
space crafts, ships, what will you do?

19. After some time we will find someone out there,
or they will find us, so lets wait for…
