Adam Warlock is the last survivor of Thanos' distorted Earth-14209, since Warlock ended up destroying him. As Thanos and Adam Warlock of Earth-616 traveled to what ended up as Warlock's Earth-20209, Warlock started acting strange in this new world so Thanos shattered Warlock's new world by killing him causing Earth-20209 to be erased. So only Earth-14209 merged into Earth-616. Whereas since Earth-616 was missing a Adam Warlock (who absorbed 616's Warlock) this new incarnation was to take his place. And Thanos mentioned to Warlock that he kept him alive in order to witness it.
