      I think they will need some kind of food but what they look like will depend on the planet they evolve on. We’ve evolved in to the best possible shape for this planet with its gravity. If gravity is greater, we might be 2 foot tall and very broad, if gravity was less, we might be extremely tall!

      The light from our sun and what’s in the atmosphere influence the colour of plants by the sort of light that gets down to the ground so that might affect what colour aliens were. If their sunlight had a different composition, they might be a different colour entirely!
