Numerous scientists since many centuries have been searching for life both in the solar system and exoplanets, such as the SETI ( Search for Extra-Terrestrial Intelligence) that uses scientific methods such as radio-transmission to try and contact aliens. All of these scientists have found much evidence that there could be or was life on other planets. The first and most popular finding of an eventuality for extraterrestrial life is our neighbor planet Mars. The central character in the search for intelligence on Mars was the scientist Percival Lowell, so said Steven J. Dick in ‘life on other worlds’.

But what made all the scientists believe that Mars carried life? 19th-century astronomer Giovanni Schiaparelli discovers canals on Mars’s surface. There is only one explanation for this: there is water on Mars, and where there is water there is life.
