Aliens probably exist. But not the way you think.
|
When it comes to
the topic of wedder aliens exist the majority of the public gets
divided in to two groups. The first group that believes in aliens and
they often describe them to be those humanoid little creatures with an
excessively large head and eyes. The other group does not believe in
aliens and dismisses the idea of life on other planets completely. The
believers will talk about UFO Conspiracy's at Area 51. Alien abductions
which always involve anal probing of some sort. And many are also
followers of alien cults where the cult leader regularly probes his
followers with his Pickle. This is really disgusting by the way, if the
cult leader is ugly and does not wash his pickle between probes.
The
non believers are right in that they recognize the whole alien cult
thing as complete fiction made up by megalomaniac cult leaders and
authors seeking a following for their abysmal ideas. Most of these
followers are ignoramuses with usually very little reasoning power.
There is a third relatively small group consisting mainly of scientists
and people that care to educate themselves. This is where you'll find
the truth. Life most likely does exist on other planets. In fact the
probabilities are that life exists on numerous planets throughout the
universe. But I can pretty much guarantee you that none of these
creatures are little humanoid aliens that fly around in saucer like
UFOs.
To get a better understanding of what such life might look
like it pays to take a look at how life has evolved on planet earth.
The earth is a carbon silicon based sphere with a large iron nickel
core. the ability of the element carbon to form long and complex chains
is very important for biology as it exists on earth. Organisms both
complex and simple are made of carbon chains. The oldest fossils
discovered so far date back to approximately 3.7-3.9 billion years ago.
Those ancient organisms where all anaerobic thermo files and our last
common ancestors. Scientist are not shore wedder life on earth
initiated in a primordial soup that got a spark from lightening. Or
wedder the earth was seeded with microbial life from a meteorite. If
the latter was the case than life would have come from somewhere else
in space, but note I said meteorite and microbial not UFO and humanoid
alien. The earth was formed about four and a halve billion years
ago. 3.9 billion years ago the earths atmosphere had no oxygen, it
consisted of carbon-dioxide, water vapor and a small amount of
nitrogen.Over time the earth cooled water condensed and formed early
oceans, and it is in these oceans that life first started to evolve.
The early earth's atmosphere about three billion years ago consisted
primarily of hydrogen, carbon-dioxide, hydrogen-sulphate and methane. A
primitive organism called cyanobacteria formerly known as "blue green
algae" started to utilize the suns energy. Cyanobacteria formed a green
pigment called chlorophyll. Chlorophyll together with sunlight is
turned Carbon dioxide and water in to carbohydrate and oxygen. this
allowed the cyanobacteria to multiply and release large quantities of
free oxygen in to the water and air. This eventually produced the
oxygen rich atmosphere that later allowed bigger and more complex
organisms to evolve in the oceans as well as outside the ocean.
The
earth is just the right distance from the sun making it neither to Cold
nor to hot. It has the right amount of gravity to hold on to a
atmosphere but not so much gravity as to crush everything that wants to
stand up. The earth's large iron core gives it a strong magnetosphere
which prevents the solar wind from blowing away its atmosphere. Once
these conditions where right life could start. There is no doubt that
the earth is not the only planet in the universe that has these
conditions or similar conditions where life can start to evolve.
Charles
Darwin was perhaps the first who brought us the theory of evolution
which plays a vital part in what we toady understand about how life
came to be and how it evolved in to the complexity that it has. At
first there were primitive single celled organisms that lived in the
earth's oceans. Over time small genetic mutations happen by chance. If
these mutations happen to be superior to life in a given environment it
will become better at surviving and therefore procreating within that
environment. If the mutation results in a inferior organism meaning it
is incapable of survival in its given environment it will die and so
will its genes. This is called natural selection or survival of the
fittest. Over millions of years life has evolved in to primitive fish
and other sea creatures as well as plants creating a tree of evolution.
The tree splits in to different branches creating a diversity of
creatures capable of survival. Once the beginning of the evolutionary
tree has bean established it becomes next to impossible for a new tree
to start from scratch If single celled organisms attempt to start new
forms of life which does happen by chance, these new organisms would
not survive because they will fall pray to the already more advanced
organisms. Evolution is not fast enough to evolve a new organism from
scratch that has the size or the tools to defend itself against the
already existing organisms. If new organisms where allowed to evolve in
a isolated environment away from the already existing organisms, they
could evolve in to something that is big and strong enough to compete
against the creatures that had evolved earlier.
Since such an
isolation did not exist on our earth every animal, fish and us humans
descended from the same evolutionary tree meaning we are all related.
Every animal is like a twig that leads back in to a series of joining
branches. The twigs that grow on the top of the tree are closely
related and branches that split on the beginning of the evolutionary
trees trunk are distantly related. For instance Homosapiens and
Neanderthals are closely related and only went on different
evolutionary paths very recently where as spiders and Humans are very
distantly related and went different evolutionary paths a long time ago
when there was only life in the oceans. There are many things that show
us just how closely related we are to other mammals. For instance we
all have two eyes, two ears, two nostrils, one mouth, a number of teeth
five digits claws fingernails. The skeletons are virtually identical
except for slightly different proportions and shapes. They all have the
same set of internal organs. And all procreate via male and female.
When you look at creatures more distantly related like Spiders and
Slugs The differences start to get bigger Spiders have eight limbs
instead of four and slugs have no legs at all. Al slugs have a male
organ and some lizards can procreate asexually.
If everything
that lives was to be removed from this earth and evolution was to
repeat itself from scratch. We would get an entirely different and
completely non related set of species. They might be asexual or instead
of male and female they might have three or more different genders.
They would not have the types of faces that we are used to. there is no
law that says how many eyes one has or if they would develop an
entirely new method for sight. Everything would evolve totally
independent from what we have now. Even thou sometimes similar
solutions might be found by evolution to take on certain challenges.
For biting for instance something hard and sharp is required. This
could be something that looks like teeth or a beak.
The reason
this whole evolution concept needs to be understood in order to
understand extraterrestrial life is because it raises two very obvious
facts. One of these facts is that evolution will happen on any planet
that has the right conditions for life, and considering the size of the
universe there will be a lot of such planets. The other fact is that
none of this life is going to look like a little humanoid alien. If
such an alien would exist it would not be an alien but a primate
related to us, and right beside us and the Neanderthals on the
evolutionary tree. Such a creature could not be from a other planet
where life has experienced its own evolution. And the notion that some
alien believers have that humans themselves where put on earth by
aliens is also a false one. If humans were aliens than so would every
other living species be on this planet. Because we share the same
evolutionary tree with them a tree that traces all the way back to
single celled organisms. And single celled organisms did not deposit
themselves on the earth with a UFO just in case you are attempting to
come up with this nincampupish argument. Humans share about 70% the
same DNA as a squirl or a dog. An alien would have no DNA in common
with any organism on earth in fact an alien would most likely not even
have any DNA as we know it at all. Instead they would most likely have
a entirely different biological coding system.
To conclude
this Article. In a universe as large as it is probability would dictate
that there will be numerous planets that have complex life some of
which are likely to have intelligent life and there will be even more
places that have simple bacteria type life forms. But not one of them
has a little green man that travels millions of light years across
space to come to earth and anal probe human beings.
PS.
Don't be a capitalist or there will be anal probing in the nether regions when you depart from life
