There is a problem with your thinking. It goes like this: you believe, because there have been false alarms in the past based on either pure superstition or an incomplete understanding of the complexities surrounding our existence on this planet that every alarm should be a false one. Unfortunately for us, there is a series of predicaments, not problems, that have been growing for years and are waiting like dominoes to fall on each other to catastrophic effect. This is what is now called a "polycrisis", namely ecological overshoot/resource depletion, the climate crisis, geopolitical tensions (that form a vicious circle with the previous two) and overpopulation. Historically speaking civilizations have vanished in the past when the capacity of their habitat was exceeded by their population, and there is at least one instance of a group of interlinked civilizations that collapsed due to climate effects.

The worst part of all these is that they interact with each other in a thousand different ways. This isn't about idle fantasies of meteors falling from the sky, divine wrath, arbitrary predictions made based on human-made calendars or just extrapolating abstract numbers. Simply put, the most basic driver of both our population and our civilization for the past two centuries is running out and we have no way to replace it. Furthermore, its continued use is turning the planet hostile to us. This is a predicament, i.e. a situation without a functional solution because of the Second Law of Thermodynamics. We have effectively free energy now that is impossible to replicate or replace no matter what we do, including developing alternate energy sources that both need fossil fuels to manufacture and provide less energy than that invested into their construction, transportation and maintenance. Even our food production is linked to fossil fuels and there simply is no way to support 8 billion people without them.

The world isn't ending, by the way. Our civilization is, though.
