Day after day, we wake up and find ourselves surrounded by life. Most of us encounter life in the human form; when we go to school, to work or to the supermarket. Other times we run into different forms of life, that do not take the human form, and that do not live in the same environment humans live in.

Venturing in space is still a long time away and in the meanwhile we should search for life here on earth. There are numerous places and habitats that have not yet been explored on earth. For instance, there was a recent discovery of a life form living deep inside caves hidden from light and heat. How is it possible that we convince ourselves "there is no life on other planets" when we do not know that life exists under our feet and it is waiting to be discovered?

If it refers to humans, then we are definitely not alone in the universe, given the fact that life, other than human life, exists on earth. On the other hand if "we" refers to life as a whole on earth, more logic would exist behind the question. The ...
