In my illustration, I have tried to capture the 3 main elements of life on earth (in my limited understanding). These are: carbon, water and solar energy. Behind my illustration of these elements is the earth. The earth, in this illustration, is connected to the universe through 'streams' of stars and galaxies. At the end of some of these streams is nothing. At the end of one of these streams is the possibility (but only the possibility) of life elsewhere. The possibility of life is illustrated by a planet that contains 3 unknown elements that may lead to life elsewhere. I have illustrated a question mark with four surrounding dots to mirror the Lewis structure of the carbon atom, suggesting that there needs to be some atom, similar to carbon (such as silicon) that could form the basis of life as long as other essential elements are present.
