Maybe the end of the world is coming soon, but "soon" in God's time, and/or the Earth's time could be sometime in the next ten million years.
Humans tend to be egocentric and think that the universe revolves around us. Our lives and our existence on this planet is merely a blink of an eye compared to geological timescales.
How old are the rocks of Steptoe Butte in eastern Washington? Quartzite estimated to be over 400 million years old. Surrounded with much younger basalt that's estimated at 15 to 17 million years old. Some of the oldest rocks in Washington State, but still not that old compared to the Earth itself.
Our "world" of civilizations and/or being cave men (really I should say being "cave people" so not to sound sexist) changes a lot faster than the world of geology. Our world is ever changing so it's always the end of the world as we currently know it.
