Hey,
We are up with our first post!!

But this is about a really common question...but yet not answered yet...Do aliens exists?

By alien I mean some form of living organism in other planets which may be at an earlier phase of the evolution as our earth went through in its past or may be super humans...

Now let's zoom out the milky way and lets see the number of stars the milky way possess...ya kind of 200 billion stars..now let's think at the best case every star do possess at least a single habitable planet ...Now as we have such a huge number of planets so we have a higher probability of existence of any living organism in any planet...Ya it sounds similar to the drake equation except it was for alien signals rather than existence but is that all...

Scientists like Carl Sagan who supported the idea of existence of any exo-planet aliens stated that given such a huge number of possibilities of existence of life it must include all the possibilities and extremities of survival how mere chance it may possess.The huge number of habitable planet will surely compensate the little possibilities of life forms.So somewhere in the galaxy life form do exists.But there are just more galaxies than one. And this assumption that earth is only special planet in the whole universe is more weird assumption.

But that's not the complete story, now think of a case, if the galaxy has spent 20 billion years, a long time, then there was enough time for the alien civilisation to evolve and to spread out or at least provide some proof of there existence like some radio signal or some weird unnatural stuff.

And this is what we call as Fermi paradox named after Enrico Fermi. Isn't that weird that we didn't get a single evidence of it or are we going to get it?

But we got a third opinion by Nick Bostrom and here is the idea may be the odd of existence of exo planet aliens be high but there may be possibility that as the creature evolves, Nature acts against it and it makes it extinct so that no species is able to spread out, or roughly nature acts against intelligent species.

But remember nothing is certain, it is all an estimation.
Hope you liked it!!
