Life on Earth exists in a single solar system revolving around a star we call the Sun. Our galaxy is called the Milky Way Galaxy and it consists of around 200 billion other stars all with there own planets that make up their solar system. The Universe itself consists of hundreds of billions of galaxies all with billions of solar systems. There is no need for other signs of life when you consider the gigantic size of the universe. Other life in the Universe is a guarantee.

∙ 13y agoIron was an abundant material when the solar system formed. It is present in all of the terrestrial planets and asteroids. Uranus and Neptune are believed to have an iron-nickel core, so it would not be unlikely that Jupiter and Saturn also had some iron in their core.
But Mercury, Venus, Mars and the asteroids in the asteroid belt may use to have life and water. Apparently on mars there is dried up valleys and seems to have life ages ago
