Many scientists believe that there must be thousands or maybe even millions of extraterrestrial civilizations in the Universe. They must be there because we have been told by evolutionists that liquid water and correct temperature are the key conditions required to breed another intelligent race. The search for aliens is becoming more and more popular. About 60 years ago the SETI( Search for Extra Terrestrial Intelligence) program was started which uses radio telescopes to search for signals from other stars and galaxies. The search is based on an assumption that any extraterrestrial civilization which wants to communicate with other civilizations will use radio or microwave signals similar to ours. So far, this program has not provided any evidence for the existence of extraterrestrial civilizations. In spite of this setback our fascination with extraterrestrial life has not diminished. This is reflected by an initiative instigated in 2015 by physicist Stephen Hawking calling for a more intensive search for aliens. So, we must believe in the existence of aliens otherwise why would we keep spending many millions of dollars, employ hundreds of scientists and use very expensive equipment, which could perform other important scientific tasks, on finding them?

When water was discovered on Mars, people got very excited. Where there is water, there may be life. Scientists are planning new missions to study the planet up close. NASA’s next Mars rover is scheduled to arrive in 2010. In the decade following, a Mars Sample Return mission might be launched, which would use robotic systems to collect samples of Martian rocks, soils, and atmosphere, and return them to Earth. We could then analyze the sample to see if it contains any traces of life, whether extinct or still active. Such a discovery would be of tremendous scientific significance. What could be more fascinating than discovering life that had evolved entirely independently of life here on Earth? Many people would also find it heartening to learn that we are not entirely alone in this vast cold cosmos.
