This will be a
short post I think (ok so it turns out that I have written 600+ words, I got carried away) but I hope that it will get as good a response as my earlier posts.
So my question this time is;
Do you believe Aliens exist? And if not, what are your reasons? Whether is religion, fear of the unknown, not enough scientific evidence, I want to know.
I believe Aliens do exist. I don’t believe they have ever come to Earth, although I’m not saying they haven’t either, just that I personally think it is unlikely. (But then again, there have been so many sightings and conspiracies it makes you go hmmm…)
Back on topic, the way I see it is this:
We are primarily matter, and matter exists all throughout the universe, from one end to the other (which may not even be possible as there may not be an “end” to the universe, but you get my meaning).
Moving a long way up from matter we are cells and organisms that require may things to survive, but the most important is liquid water.
And liquid water can only exist if the planet, moon or any celestial body, if just right. And these “just right” planets are also known as Goldilocks planets (clever huh? (I have provided a few links about Goldliocks planets at the end if you want to do some further reading at what they are and the ones we think we have found.))
Perhaps the most famous of these planets is Gliese 581g. Gliese 581g is a planet that lies around 20 light years away and it orbits a red dwarf, a dying star, and it is in the stars habitable zone.
The main problem with this planet though is that it turns at a speed relative to its orbit around the sun. What this means is that one side of the planet is always facing toward the sun, which obviously means that the other side is always facing away.
Which obviously is a strange concept, and indeed it is. What this means is that the side that faces the sun is too hot and the side which faces away is too cold.
But the interesting thing is that this means there is a thin band of temperature which is just right (which means that the actually world as a goldlocks zone too). What scientists believe is in this band, which is going to be a constant perfect temperature, liquid water could exist.
And as you know from earlier, liquid water is the key to potential life. But what does “life” mean in this sense.
Of course if there is anything there it could just be microscopic bacteria, but they are “life forms”. And of course if there is a chance there is microscopic bacteria there is also a chance that it could be evolved. It could be a type of mammal, a fish living in the water etc.
Or there could be no life.
But that’s not to say because there is no life on that one planet there won’t be somewhere else. The universe is immeasurable, at least with today’s technology, so out there somewhere there is more than likely a planet which rotates around the sun just like Earth and is the same distance away as Earth, has an atmosphere just like Earth and may even have life which blogs just like we do. They could be cave men still, they could be an advanced race with blasters. They could be germs so small that our microscopes couldn’t even see them, but they could still be there.
And that is why I believe aliens exist. Even if they are just a speck in a primordial soup, still in their early days of creation.
Entire races could have flourished and died along with their Sun (as we eventually will) without ever developing the tools or the technology to make contact.
The universe is big, and we humans, are so so small. Isn’t that scary?
