Staying with your Old Trek example, in the timeline where they didn't go back, Earth was destroyed by the probe. So, if the timeline is split in two at the point of their (arrival or not) in the past, in the original Earth dies and in the new it survives (less Gillian and two whales in the past). You could have both timelines merge back when they return to the future, and that's the best way I saw to resolve this problem so far, in ST universe, without making everything pointless (suggested in the ST:DTI book series). This solution won't work in New Trek, though.
