Assuming we don't use one of the thousands of possible ways for us to kill ourselves, life on Earth should survive as long as there's an Earth. Land life however is not gauranteed, but something will be squirming here foe a good long time. I think it may possibly even survive solar expansion, as by then we (or our successors) will have found a way to move the planet, and maybe even the wisdom and foresight to actually do it before the first flare touches the surface (not to contrast them with us short-sighted moderns or anything).
