              If we Humans wanted to survive for long and let our species thrive as long as possible then we shouldn't waste time. Fighting against one another should be set aside. If we only have one goal then it's possible that our species can live longer.

                                      It will probably be a Red Dwarf; a tiny kind of star.

                                                      When u look at how many years a red dwarf lives... then u look at yourself how many years u live.

With the technology (this is what it comes down too, us as a species actually becoming a Type 3 civilization), we can (theoretically) create and design new stars.
