Do aliens (not) exist?

For generations we have asked the question “Do aliens exist?”, the real question should surely be “Why would aliens not exist?”.

Let’s think about where we are and how we may have got here, to this earth?

Before this expanse of the galaxy, there were no stars, atoms, nothing at all – just a singularity.
The entire universe probably started as a super force that was itself very tiny but very hot and dense too, no more pressure could be built up inward so there was a big bang, it was not of a massively ongoing explosive force as the name would suggest but more of an expanse of space, setting new boundaries and waypoints outwards from an energetic inner point.

We are not sure how the big bang was initiated although we can see the trailing ends and the markers of it as space ripples with time as well distorting it at times.

Eventually, the outward force slowed down, objects in time and space clumped together to create astral bodies, these bodies became bigger and bigger with massive amounts of energy transforming them from molten masses that cooled to create solid environments, not all of the bodies cooled with many still burning brightly becoming suns with ever-moving super hot interiors with just the crusts cooling but not by much.

Other lumps of the original matter were thrown far into space in small pieces only to rejoin due to chance as well as to gravitation pulls from the bigger bits, eventually, after lengthy times these bodies became moons, meteors, asteroids and comets..

There are lumps of material of all sorts in space, regular metals like iron, copper, tin, aluminium, there are even planets made entirely from gold, silver and diamond with some having liquids and gases – there is everything and everything in between.

Not all of space is inhabitable, some areas are too hot, some too cold, on earth we happen to be in the the ‘goldilocks zone’, with a proper name of the ‘circumstellar habitable zone’, these are areas of space where life is possible that normally range around stars with planetary surfaces that can support liquid water with a sufficient atmospheric pressure, as well as that, not one that goes from a compressed to an elongated mass due to insufficient size with close proximity pulling from orbits.

After a very long time space was settled, planets formed, cooled then found orbits around stars creating complex systems. In all of this, there were leftover organic compounds, organic soups that collected then basic forms of life were created by chance, they were then able to co-exist and reproduce, evolving from single-celled to many-celled beings.
In the early times species came and went, at times it was due to the fittest and most adaptive surviving, in other life there were events where most of the entire populous were wiped out, like as in with the dinosaurs on planet earth.

From the cracks, new life evolved, insect, animal and human, going on from basic beginnings with simple objectives to the now complicated world and societies we live in where everything has its place and is categorized

Here on planet earth, we are surely not the only inhabitants of the galaxy or bigger universe, in the milky way we are located on one of the trailing arms, there are between 200 and 400 billion stars and at least 100 billion planets. We are just one of those planets and just because we are in a goldilocks zone does not mean life cannot exist outside of that – there are many goldilocks zones, and areas outside of those – just like the sea creatures of the earth that can live in a super hot and super cold environment which we are only just learning about. We know very little.
