Don’t be too modest, we will take countless species with us. Some are already relegated to museams due to nothing but human interference. Yes the giant rock will persist but we will disturb enough life to seriously jeopardize the future of many if not most forms of life.
Unironically probably something like that. Nature will take what we give it and keep going best it can, the ashes of the old world will fertilize the new one, and it wouldn’t be the first time nature on this planet has done something like that.
