Life can be found in almost every corner of our planet Earth. Leaping, swimming, flying, sprinting, slithering, crawling or rooted firmly in place, organisms appear, die, and are replaced by new generations and new species. Whether a similar bounty of life exists elsewhere in the universe is one of the oldest and most reappearing questions of science. Considering the wide breadth of the universe and the countless stars it contains, the odds would seem in favour of the answer being "yes, life does exist." But there are some arguments which we would have to discuss in order for it to be the real answer.

This major question has become an important subject of astrobiology, in which many scientists are involved and a majority of their work has to do with plenty of hypothesis and no credible evidence, leading to the unacceptance of the scientific communuity. There are a few main hypothesis regarding the origins of these life forms: 1. They showed up on their own in different places in the Universe 2. Life can show up in one location then spreads to other different planets which can sustain life.

We, as a group, has agreed that there are extraterrestrial life forms in the galaxy. There are a few scientific searches that have proven this and they have found planets, satellites (or otherwise known as a moon), and floating space rocks.

Recently scientists have proved the existance of aliens. According to CBS news, the meteorite that crashed in northwest Canada almost seven years ago might have been able to host the very earliest life forms, according to NASA researchers, which opens the door to the possibility that life could be present elsewhere in the universe. The Tagish Lake meteorite is unique. Tiny bubbles in the rock are organic globules where the universe's earliest life forms could have been able to live. The meteorite is 4.5 billion years old –older than the earth. This meteorite is unique because it was recovered froze and some of these samples came to scientists still frozen. No one knows what is the source of the organic material in the meteorite. There have been sightings. A flying disc was seen by pilots, crew members, and a bunch of other people at the Chicago O'Hare Airport in November, 2006. Scientists have found alien looking skulls, ancient monuments that we would have trouble building today, metals that don't originate on Earth, they were completely spherical and well fabricated. But one thing is for certain – those who question extraterrestrail life has to keep quiet this time. The proof is real and verifiable. Europa, the sixth moon from Jupiter has been speculated to contain life under its liquid oceans underneath its surface but there is no evidence that proves this. In the 1970's, scientists have stated that life would need to have energy from the sun, such as the plants on Earth. So how could this sunlight reach down beneath Europa's underground oceans? Life in these oceans may have consumed detritus (waste) falling from the surface of the water. An expedition which led scientists to visit underwater volcanoes have proven that life does not have to have sunlight, even from underneath oceans. Underwater life just needs water and something other than the suns energy to live. Many people also believe that life had existed on Mars. A meteorite which was expelled from Mars landed in Antartica. Scientists had examined this rock and had found frozen bacteria like structures on this rock, believing Mars did contain life. It is entirely possible since Mars has canal-like structures which could have contained water and polar ice caps just like the ones here on Earth.

But Mars was one of the origins in which many people believed alien life forms in the shape of a humanoid lived. They were green, lizard like and out of this world. As a group, we do not believe that alien life forms exist as there is actually no evidence of these creatures. Many speculate that these aliens are very smart beings and have actually created many things that is past our technical knowledge we have today. People have stated that they have been abducted by them and have been experimented on. There are plenty of fictional things that have to do with these aliens, such as that of Area 51 and Unidentified Flying Objects. But during the course of evolution, these microscopical life forms may have experienced such a process leading them to look like the aliens we see in science fiction. But, as we know, there is no evidence what so ever. Of course, there is always the chance that extraterrestrial life will find us first. Perhaps not in the form of a visiting UFO, but a radio transmission from an advanced alien civilization is still considered within the realm of possibility. If extra-terrestrial life forms did exist and have undergone evolution, had become amazingly smarter and more advanced than us through technology, then we might run into these things sometime. UFO's have been claimed to look like the ones in science fiction films as their technology is beyond ours. They even have a stereotypical look to them if mentioned, flying saucers or disks for their space craft. Wide eyed, big head, slits for a nose and a grey body for those martians that have been stereotyped. And do martians exist in Mars...? Scientists believe if Martians ever existed, they wouldn't be the little green men of our imagination. Water probably didn't exist on the surface of Mars long enough for anything other than very small, bacteria-like life forms to develop.

E.T is a famous alien from the movie, E.T., hence the name. Could alien life forms look like this? Or microscopic life forms found in outer space?

or like this.....
