Being prepared for emergencies is prudent. And most contingencies require the same basic preparations and planning. A store of non perishables, water and a way to purify more, a good rifle and ammo, clothes for adverse conditions, perhaps a generator etc are all good to keep on hand. But the number of times in human history the world has "ended" can be counted on one hand. That time 10k years ago when the human population had a big bottleneck, maybe a super volcano. The bronze age collapse is another. The fall of the western roman empire. That's about it. But there are many more smaller events that still warrant emergency preparedness. Catastrophic weather, civil unrest and war count.
