Or more specifically, Life on other planets.
I do not, for one moment, believe we are ‘alone’ in this universe. Life came into being on our own planet, albeit with a specific set of criteria, but just because we haven’t found proof of other lifeforms, it doesn’t mean it doesn’t exist… somewhere.
Alien Life Forms
Science fiction is rich with other life forms, and a quick search through Google images reveals just how wide and vast our imagination is when considering other forms of life – little green and grey men with small bodies and elongated or over-sized heads, human shaped aliens, insects, robots, a jelly-like blob… As with the other elements of science fiction I have so far discussed through this challenge, our vision of what constitutes an alien has changed as our own science and knowledge develops.
