This review discusses the possible microbial habitability on Mars, assuming variable conditions and ingredients favoring life on Mars. Westall et al (2013) analysed certain considerations to hypothesize that the potential emergence of life on Mars over time was not constant. There have been mineralogical and geological evidence supporting the availability of water and as discussed, there may have been possible routes where martian habitability could have flourished. Although there is adequately

latter is the panspermia theory which suggests that life did not originate on earth; but rather came to earth from somewhere else in the universe. It is the idea that the ingredients for life are found throughout the universe and are able to initiate life given a habitable environment. While this theory may seem improbable to some, increasing evidence suggests that this idea may have more truth to it than some may believe. In order for life to have come to earth from somewhere else in the universe

Astrobiology Astrobiology is the study of life outside of Earth. Life on other planets has yet to be discovered. However, scientists believe there is life somewhere else in the universe. Before searching for life elsewhere, scientists attempt to discover how life started on Earth. The Earth is truly an optimal location for millions of types of life. The sun is at a seemingly perfect distance from the Earth. Scientists look for rocks to find microbes in fossils. Sedimentary rocks can contain rock

August 12, 2012 I watched the CNN news broadcast for What’s next for Mars? Searching for Alien Life on Mars. (CNN [CNN], 2012, p. 1) CNN interviewed Author Lawrence Krauss about what the next steps will be for the rover Curiosity on mars.

Lawrence Krauss thinks we are cousins of mars and we could actually be Martians.

Many of these anomalies will remain unsolved unless we as a society become open to the possibility of change, open our minds and our eyes. The answer to the question "Are we alone in the universe?" has been unanswered and may remain so until scientists are no longer heavily scrutinized for researching the topic. Mainstream science has and will continue

only place to seek for non-human life now is other planets. Is there any hope for finding it? There are a great number of theories concerning extraterrestrial life. According to the “rare Earth hypothesis”, the conditions on Earth are close to unique and the possibility of them taking place on any other planet is close to zero. However, this theory takes it for granted that the appearance of life requires conditions identical to those on Earth. But is it true? If life on other planets exists, it may

ancient Peru, archeologists have uncovered mummified remains with enlonged skulls”(History.co.uk). Scientists claim Mars once supported life and has signs of water underground”(Jasper Hamill). Aliens have to exist because of how large our universe is. Scientists have found alien planets that have an atmosphere and could support life. “Water is a key ingredient for life and is very common in our solar system”(ABC News).

As we know, the people who explain about forms of life from other planets can be either terrifying or thrilling to the audience. In Christopher C. French's article "Close encounters of the psychological kind" states about four different kinds of psychological explanation due to each kind of encounters with the aliens. French, a psychology professor and who does Anomalistic Psychology Research Unit at the University of London, first talks about how the sightings are one of the created images that
