It is concluded that martian meteorites do provide insight and valid evidence for extraterrestrial life. INTRODUCTION The question of life beyond Earth has been debated upon since over 2000 years ago, when Greek scholars first discovered that our planet was not alone the universe. Out of the eight current planets in our solar system, Mars is said to be the most similar to Earth, suggesting that it is the most probable planet to have encompassed life, if any. Although today it is cold and arid, the red planet was once warmer and wetter with a thicker atmosphere and could very well have allowed life to form. Martian meteorites that have landed on Earth contain evidence that justifies the presence of life in space.
Scientists believe that the earth’s gravity caught some of the debris and pulled it into the earth. Scientist Digregorio, Barry E (B4) stated that inside the debris of falling rock, were microorganisms. He notes that the microorganisms may have been the very start of life, as human civilization knows it. There is no way to prove his theory true, but it is a strong possibility. Similarities in planets led scientists to believe there is a common bond between Venus, Earth, and Mars.
Also in May 2009, images of an unmanned spaceship showed what it seemed to look like drops on the surface that appeared to be built during the time of the mission of the spacecraft on Mars. Another place that has scientists believes life is a moon of Jupiter, Europa. Some of them believe that there is a giant, active salty ocean beneath its surface. This indicates that there is significant activity underneath that frozen surface. Another sign of life in Europe includes formations that looked like icebergs emerging from its surface, suggesting that oceans once covered the planet before it froze.
in Begley and Rogers 58) The problem raises when it is proved that those kinds of minerals and organic molecules found in the meteorite, which fell from Mars about 13,000 years ago, can also be formed during nonbiological reactions such as very high temperatures. For us, the common magazine readers, it is difficult to deal with these two positions: the final acceptance of extraterrestrial life, which is the
One of Jupiter’s moon, Europa, is currently being taken into consideration for exploration. Doing so is many years from happening but the encouragement from the results of exploring Mars has lead us to consider far distant planets for exploration, when just a few decades ago the notion that there was alien life out there was considered ignorant. If we were to find a planet that could support life forms in some way, it would allow us to colonize other planets and expand our horizons even further than we imagined.
In 1994 scientists discovered fragments of meteorites which may in fact prove that signs of early life existed on Mars. Many of these meteorites are found in the Antarctica, extremely cold weathers aid in preserving and fossilizing the fallen meteorites for millions of years. In order for scientists to conclude that the meteorites are from Mars and contain signs of fossilized life or traces of it they must provide sufficient evidence to support their theory. Today, a meteorite from Mars is being closely scrutinized by earthly intelligences. The famous meteorite to bare significant signs of life is the Allan Hills 84001 (ALH84001), classified as one of the meteorites thought to come from Mars.
We flew to the moon in 1969, but now we have the power to fly to Mars. In the near future, Terraforming Mars will not just be a science fictional idea. It could actually be done. It is a long process to do, but it can be done. Imagine the power of technology hundreds of years from now.

The radiation Jupiter produces made it hard for Galileo to come close to the inner moon and scientist thought it would be best to save that for last.

They could be tested for things such as evidence of fossilised organisms. Another, possibly slightly far-fetched hope is that we may find simple organisms like bacteria actually living on the desired planet.

Another idea is that UFO's are not really from other planets at all, but created right here on Earth.
Scientists have studied the Moon to try to give it an approximate age. The youngest moon rock which scientists have studied was radioactive dated as 3.16 billion years old, while the oldest dated rocks were dated 4.6 billion years old, which also indicates that the Moon is the same age as the presumed aged of Earth (Gallant 117). If the Moon were to be colonized, there are two main components needed to sustain human life, not only on the Moon, but everywhere. These two important needs are water and oxygen. Without water and oxygen, life will cease to exist.
