(I) The possibility of extraterrestrial life is increasing and some recent developments are supporting the possibility. (II) For instance, scientists are continuously discovering new planets which offer suitable conditions for forms of life similar to ours. (Ill) Such life forms must be quite different from the one on our planet. (IV) In addition to this, some biologists have already shown that intergalactic space has the same substances that are considered to be the source of life. (V) Thus, the same conditions that favoured our planet might as well have worked in some other parts of the universe.
