What if we got to the point were we had all the technology to change a planets' environment as our own, breathable air, needed pressure, low radiation...gravity we can handle. Well what if at that stage we sent in other species other then our own to colonize the planet in hopes that they develop evolutionary there and perhaps in hundred thousand years will be smart to explore space and be like we are? :bugeye: I always believed that species diversity is the key to achieving balance in life and maximizing chances of life to exist. Say we found a water planet....or even better moon Encelados with its underwater ocean and instead of going there ourselves, sent in the dolphins...we would set up robots to care for the moon to make sure it was not destroyed by us or any impacts, meanwhile we would wait for a natural development of dolphins intelligence. They are already as smart as the chimpanzees...perhaps even smarter. Perhaps here on Earth the environment did not let them fully evolve...but on oceans of Encelados it would allow them to evolve.
