الأرض - כדור-ארץ -Erath .miracle (creation): possible in other planets impossible .coincidence (DNS) possible in other planets (Panspermia) .natural process (Self-organization of the material) ----------------------------------------------------------------------------------------- .Right kind of Universe (BIG BANG) : He+He+He = C (three in one, rare; happens in resonances) He+C = O (more probable, but stopped) .Right kind of Galaxy: Enough metals (not small, elliptical or irregular) Open Clusters are too young, Globular Clusters are too dense (23/100000) .Right position in Galaxy: Not in center, edge or halo .Right kind of Protosolar Nebula: Enough light elements (H, He) to form a star, and enough metals to form terrestrial planets. .Right mass of Star: Long enough lifetime (10-12 billion year) Not too much UV (59% of the stars are smaller than Sol) .Stable Planetary Orbits: Giants do not create orbital chaos .Right distance from Star: Temperature: water Far enough to avoid tidal lock .Right planetary mass: Retain atmosphere and water Enough heat for tectonics Molten FeNi core: magnetic field .Right amount of Carbon: Enough for life, not enough for runaway greenhouse .Right amount of water: Enough water to 5-6 billion years, but not too much to form continents for plate tectonics and complex life .Jupiter: Few giant impacts: (but they are necessaries to accelerate evolution) No global sterilizing late impacts .Big Moon: The right tilt: seasons Plate tectonics: CO2-silicate thermostat .Comets: Planets in the HZ contain only minor amount of water and carbon: they came from comets .Mars: In the HB life became extinct on Earth, (3.8 billion years ago)because the impact heat boiled the oceans, but this did not happened on Mars, there was less water. The life came to Earth back from Mars. 10% of Earth's existence had complex life دياب طاهر - דיאב טאהר
