It is not possible to say whether there are aliens out there or that we are alone. We haven`t made any real undeniable contact with aliens and because the universe is so vast that we haven`t and couldn`t have checked everywhere for life. Some people say that crop circles are messages from aliens but why fly all this way, leave an obscure message and then fly away again. People report that they`ve been taken by aliens but they are dismissed as unreliable and attention seekers.
Until we get an alien mothership hovering over a major city, UFO abductees will continue to be dismissed. The only way I can plausible see us being the only lifeforms in the Universe is if we are at the centre of the Universe and that chemicals exist on our planet that don`t exist anywhere else which is highly unlikely. The most important chemicals for life on Earth are Oxygen, Carbon, Hydrogen and Nitrogen. All three of those chemicals have been spotted on in space. Oxygen has been spotted in a star forming region of Orion, the Hunter constellation, you can read more about his on the BBC News website.
There is a growing belief that we, humans are aliens to this planet, that we came to Earth after hitch-hiking on a comet, that theory is called Panspermia. The theory has since taken a knock after the rosetta space probe landed a probe on Comet Churyumov-Gerasimenko and found that the comet was made up of the wrong type of chemicals that was required for life. The theory gathered support when it was proven that amino acids can survive high impact collisions whilst onboard such objects. Attention has now turned to asteroids but don`t expect an exploratory mission to any asteroid any time soon. The experiment was carried out by NASA in America. If we arrived here by hitch-hiking then there`s every bit a possibility that alien life like here on Earth exists elsewhere. Aliens would not probably look anything like humans or animals that exist on this planet. They`ve only looked at one comet but there`s nothing to say a different comet could be made up of different materials, materials that could contain Amino Acids. If we did come from a comet from the far reaches of space, there`s nothing to say that he comets didn`t split into two, one part coming to Earth, the other going to some other distant planet elsewhere in the universe. At the beginning, the lifeforms on both planets would be the same but environmental conditions would cause both spieces to change in appearance. There are those who believe that we originated totally on Earth with no alien help from elsewhere. Maybe human amino acids arrived on the comet/meteor that killed off the dinosaurs. The suspected meteor crashed into the Mexican Gulf and as it hit the sea, our amino acids were washed off. Life on Earth was organisms for over a billion years before something happened and we started on the path to walking on the ground rather than just under the sea. For more information on the evolution of life on Earth, can I suggest you look at the BBC website which has an indepth section on it. Over the years the amino acids grew and developed into humans. Other suggestions are that we were seeded here by an alien race from other worlds who wanted to preserve their own kind. If we were seeded here by aliens why have they not left any technology behind for us to use ? Why did they put us so far away from anywhere else ? Why haven`t they come back to see us?
For many years, people thought that Mars could contain alien life forms. One of the reasons for that is because its so close to Earth and people had seen canals on the planet which once could flow with water. Martian aliens could`ve once existed on the planet many centuries ago when the planet had a strong magnetic field to protect the aliens from harmful sun rays. When the magnetic shield collapsed, the atmosphere became harmful to alien life. The only possible alien life forms that could exist on Mars are crude organisms, not ones that could attack Earth with their death-rays. National Aeronautics and Space Administration (N.A.S.A.) and its partners including European Space Agency (E.S.A.) (E.S.A.). and other space agencies have spent millions sending probes and landers to the planet to look for simple single-celled alien lifeforms. Whilst they have found Methane on Mars, they haven`t been as bold to say they`ve discovered definitive evidence of life on Mars. N.A.S.A revealed they had calculated how much water Mars once did have before it changed and the result was that Mars had a large ocean once. There are people plannng on moving to Mars, to build colonies, we would become aliens to Mars. We are only scratching the surface at the moment, we really need to get to Mars to discover if a Martian alien race ever existed.
On Earth, the main ingredients for life is Oxygen ( for animals ) and Carbon Dioxide ( for plants ), it should not be assumed that this is the case for alien life on other planets. Aliens metabolism might survive on Nitrogen or Hydrogen rather than Oxygen. An alien life form may well find that our planet is toxic as we would theirs. On our planet, there have been places discovered where the environment is toxic to us but life has existed. There are vents under the sea which although toxic to human, life has found a way to exist. The Jupiter moon of Europa is an ice world where people think that under the crust, alien life forms could exist. Space agencies are planning to send a satiellite to examine the Moon for existance of alien life-forms.Whilst all life on earth with the exception of a few spieces ( mainly simple lifeforms ) requires a male and female of a spieces to reproduce. It should not be taken as though an alien race will have the same number of genders. The alien race might have one, two, three or more different genders.
Everything in this section is pure conjecture as no plausible contact has been made. Let`s suppose contact with an alien race has been achieved on a grand scale and that people cannot discount or deny it has occurred. What would they be here for ? Would they be peaceful or hostile ? What would they look like ? A lot of science fictions programs have aliens from other worlds as human like. They could very well be our long lost cousins but they are just as likely to look totally different. We are all used to bipedial aliens, but they could be tripedial or walk on all fours. The aliens might be waiting for us to show we are technically advanced and merit first contact, something that is a made a big deal of in Star Trek as the First Contact Directive which Capt. James Tiberius Kirk has on a number of ocassions broken.
Now is just about as good a time for aliens to make their appearance as any other time. The aliens might already have visited and thought `Nah!`. For the past fifty years, we`ve been sending out signals from television and radio, which by now these signals might have reached a planet with alien lifeforms. The signals have definately reached other planets, however whether they inhabital is not known. The picture at Zidbits when you click on it shows how signals have gone and t.v. show Miami Vice is now reaching Fomalhaut which has an Extrasolar Planets (Exoplanets) orbiting it. Fomalhaut b is unlikely to contain alien life forms but you never know. The Aliens could possibly have managed to interprete the signal and decided to investigate. Amongst those signals would be images from the World Wars which might put the aliens off. The aliens might be waiting for us to get to a high level of technological competence before we meet them so they don`t interfere with our progression. Some people believe we may have already been in contact with aliens and they helped our earlier civilisations such as the Incas, Aztecs and Egyptians. They point to the fact they all had Pyramids.
In 1977, scientists from the Search for Extra-Terrestial Intelligence (SETI for short) received a signal from star in the constellation of Sagittarius which became known as the Wow Signal. It was a signal that no-one was expecting and soon everyone with a telescope was trained on that area of space where the signal had come from. Alas, no new signal was received from that area of space. People thought it might be a signal from an intelligent lifeform out there. Ref: Daily Mail
Whilst we all hope that the aliens are friendly like Vulcans from Star Trek, we would need to be prepared in case they turn out to be life destroyers like in Independence Day. According to Prof. Stephen Hawkings, from Cambridge University, believes that aliens would be nomads, moving from one planet to another, using the resources and moving on and conquering new lands. He cites what Europeans did when they moved to the America and that Native Americans didn`t come out well. Ref: Brainy Quotes.
The more technically advanced a race is the more aggressive they are. They could come here, take us prisoner and use us as an alternative food (V) supply or simply just enslave us. They might already know where we are from the television and radio signals that we`ve been beaming out into space for the last 100+ years. A alien race between here and just over 100 million light years will now be receiving our signals. They might even be sending a signal back which hasn`t reached us yet.
The most famous alien encounter to grab peoples attention is the incident that happened in Roswell, New Mexico. That incident has spawned many merchandising and lore about the area. It features in numerous television and films including its own television series, named simply Roswell. The American Government tried to draw a line under it by saying it was a crashed weather balloon but theorists are not convinced.
Across the pond as they say, Another incident has garnered a lot of attention, events surrounding a mysterious object near R.A.F. Bentwater which was being used by the American Air Force as a forward base at the time. The events caused such a stir that it caught the attention of the Government at the time, prompting a Lord to write to Michael Heseltine, the then Defence Secretary for comment.
