As far as we understand our planet we enjoy
the benefits of habitable eco-systems, fresh water, and a means to
produce foods. These things would be the most likely reason for
an alien invasion. Assuming that we are not alone in this
Taken to account that there are roughly 100 billion stars in our Milky
Way galaxy, the probability of life on other planets is a likely
one. Also the infinite numberof parallel universes, there the
possibility of life on other planets
is expanded quite a bit. Extraterrestrials would have quite a bit
of searching to do just to find our big blue ball in an infinite sea of
possibilities, in this case.
The reasoning behind an invasion could stem from any number of
things. Their own planet could be in the grip of over population,
that they have depleted their own native resources and drained the
planet. Over pollution is as
well another possibility for their migrations. If there were
resources native to only a few planets, Earth included this would be
another cause for invasion.
Maybe they received a great Zales promo code that they want to cash in. Or perhaps it's an exploration group touring the galaxy, much like Christopher Columbus and Vasco da Gama. While getting discounted jewelry is probably not a likely reason for an alien invasion, it does serve as a reminder that there are a million reasons and not all of them necessarily involve plundering of resources or other hostile acts.
The existence of life within our own Solar System
Scientists have puzzled over whether or not
life other than ours is existent in this corner of the
neighborhood. They look to other local planets and moons, such as
Mars and the satellite of Jupiter, Europa.
Mars, with its signs of flowing water in its past is the target of
current research. The two research vehicles, Opportunity and
Spirit currently exploring Mars, have confirmed the presence of
liquid water in the planets history. It
is quite possible that it had harbored life at one time, and may
currently have microscopic life today.
The moon Europa with its primordial oceans hidden beneath thick layers
of ice could be the home to many water dwelling organisms. It is
widely taught that water is where life begins and evolves from, why not
under the icy face of
Europa. With a surface that is estimated to be only 30 million
years old, it is not likely that an E.T. invasion would begin here.
If in fact there is life on other planets, it
does not necessarily mean that it has the mental facilities for higher
motor and thought processes. It took mankind at least 1 million
years to evolve into what we are today, and we have not
begun to scratch the dust on the surface of scientific
exploration. But who is to say that another form of life and
civilization could not evolve into something far greater than we are
now in less time.
Today's technology is still prone to quite a bit of mishaps as we are
still in the baby steps of exploring just our own Solar System up
close. Better propulsion systems and protective vehicles and
suits will have to evolve in order to explore our closest neighbor
besides our own Moon.
Our universe is theorized to be one thousand
trillion trillion (1,000,000,000,000,000,000,000,000,000) meters,
should our planet be found in the vastness of possibilities, how would
we be reached from the depths of space? Traveling at a year at
the speed of light one would have gone ten trillion kilometers
(10,000,000,000,000) one would have to possess superior technologies
that could propel them at faster than light speeds, and/or through
"wormholes". A theoretical distortion of space-time in a region
of the universe that would link one location or time with another,
through a path that is shorter in distance or duration than would
otherwise be expected. If one were able to harness faster than
light speeds, faster than 300,000 kilometers per second as well as
travel through wormholes, then an invasion would be quite possible
within a few years as opposed to a few million, billion, or trillion
years. Physicists today are coming closer to the answer of this
question although the technology is something out of our current reach.
Would we be able to protect ourselves?
Were astronomers able to see an incoming
threat it would give us time to prepare, though at that point in time,
we would not know if they were friendlies or hostiles.
Considering that astronomers have a difficult enough time tracking near
earth objects the likelihood of them spotting a fleet would be small in
Given the technologies that these beings could possibly possess, or
other transport options that we couldn't fathom, it is quite likely
that they would possesses weapons that would remove us completely
without endangering their new possible home. In another case,
they may even just kill off the excess and use the rest as slave
labor. Such fantasies as seen in the science fiction books and
movies where humans won the day through whatever means would be exactly
that, fiction. An intelligent species would have taken the time
to study this planets physiology and technology to learn what viruses
and possible threats that were resident here and take precautions.
In the event of an unknown threat, we would have no hard information on
how to defend ourselves against a threat such as this. Being an
unknown enemy is the best tactic that an enemy has. We would
either kill ourselves, and the planet with nuclear weapons in the
remote chance that it would remove the threat, game over for everyone.
