In theory, life could have emerged on Mars or Jupiter's moon, Europa, where they seem to have an underground ocean. "This is consistent with human exploration of the solar system, these intelligent creatures could have evolved in the sea of Europa," said astronomer Jacob Haqq-Misra of Pennsylvania State University.
Alternatively, Haqq-Misra said that intelligent extraterrestrial creatures traveled from distant star systems and live in the solar system. "They may live in a secret base on Mars or the moon or the asteroid belt," he continued.
Given this scenario, what would happen if an alien race is discovered? Today many reports appear to report sightings of flying saucers that continue to invade the human psychology. Of astronomers to anthropologists UFO watchers have their screenplay.
Voyage of discovery
According to a senior astronomer at the SETI Institute Seth Shosta in Mountain View, California, contact the most likely scenario is that an alien race which was found to be very primitive. This assumption is based on reality, the universe can be explored not show signs of advanced creatures hide.
Furthermore, given the difficulty of space exploration, it is estimated, the explorers there will be far more advanced than the creatures were found. This facilitates the manufacture of the protocol for the first meeting, if time landing on Mars or Europa is found alien from trilobites, "The thing to do as did Darwin, collect samples and bring it to Earth," says Shostak.
Seven steps
Shostak said the size of the universe and nature makes it difficult to face the scarcity of living creatures are made of two competing intelligence. Author Robert Freitas alien contact scenario describing the U.S. military (U.S.) in 1950 developed a seven-step procedure by first logical steps.
According to these steps, people will begin to perform remote monitoring and data collection, and then finally transferred to a secret visit with the aim of measuring the performance characteristics of alien vehicles and weaponry.
If all goes well, man made a brief visit, securing specimens of plants, animals, and intelligent creatures. Furthermore, people will introduce themselves and show the existence of non-hazardous waste. Finally, if all goes well, there's no reason both races this contact lead to disaster.
"Say a future mission to Europa reveal irrefutable evidence of intelligent beings or civilization," Haqq-Misra said. Exploration continues and eventually humans will make contact, he added.
"However, the 'precautionary principle' to delay human exploration to confirm the robotic exploration of Europa harmless people," he said.
Alien colonize
On the other hand, there is a second scenario in which Haqq-Misra alien race twice more intelligent than humans. Just like an ant who can not understand human behavior, humans can not possibly understand how this race would react in humans.
"(Astronomer) Carl Sagan thought, aliens could travel between the stars and they do it for the aggression and war and so on," said Shostak. According to him, aggression evolved as the nature of the inhabitants of the earth because it helps people find and protect the resource.
Although an alien may be growing in totally different conditions, the pressure to secure the limited resources likely will shape their behavior as well. "I guess, would be limited resources anywhere in the universe," he said.
If Sagan is correct, then the people who met a wise man will treat with great consideration and respect, while they will use technology to ensure humans treat it the same way. (Taken from any sources)
