What did Earth have that the other planets did not have? Nothing spectacular - only the proper size enabling gravitational and electromagnetic balance. Nothing extraordinary - just a position with respect to the Sun that enabled Earth to establish a temperature range where complex molecules could be formed. These arrangements of matter enabled the solar system to advance to Earth's creativity. Had this particular amount of stellar material not congregated in such a size and at such a place, the solar system would probably have remained a lifeless place through out its billions of years of existence, but such balance and such possibilities did emerge, and Earth became the advanced edge of cosmogenesis in the solar system.
