Earth and Mars are planets positioned next to each other in the solar system, although in terms of closeness, earth is closer to venus compares to it closeness to Mars. Earth and Mars have the same materials make up, similar origin. The only different between Earth and Mars in term of material composition is just the quantity, this posed a question in people mind, since Mars and Earth have the same material composition although in different quantities, why is that life in many forms appears on the earth and not mars?.
