SS: it seems that solar systems with two habitable planets are rare .. our solar system did not originally have two habitable planets .. that is because mars did not originate within our solar system .. mars was originally orbiting a brown dwarf planetary system that wandered into our solar system through a black hole wormhole from andromeda galaxy.. the reason they came here was because they could since they are all powerful with their ancient technology so they came to mine this newborn solar systems planets and moons.

SS: the andromedans commited suicide because they were completely annihilated when the newborn  proto-star, our sun, suddenly ignited and cause the martian cataclysm .. now mars is captured into orbit with our solar system and just happens to be within the habitable zone .. it would be a great advantage against the andromedans to have two habitable planets and this is why colonizing mars and finding it’s secrets is a priority.

SS: the evidence found in the solar system i think the andromedians were not here very long .. only one moon the methane moon titan has been found so far with mining .. and maybe mercury have some evidence of mining .. most of the mining space ships appear to be in orbit around saturn so far .. one other planet might show signs of mining which is pluto considering all the recent objects found in its orbit . for now colonize mars and find the andromedian technology there should be the priority and then the space station iapetus and the saturn mining ships.

How ‘Tatooine’ Planets Orbit Twin Stars of Kepler-47 (Infographic) 28 August 2012 With binary stars at their center, the Kepler-47 planets have two suns like Tatooine, the fictional home world of Luke Skywalker in the “Star Wars” universe. Kepler 47-c orbits within the habitable zone of its parent binary star. Its orbit is the largest yet found for a planet outside our solar system.
