    The thing that is harder to grasp is the scope and scale of the timeline. Like 252 million goes into 4.5 billion nearly 18 times. This means 252 million is recent on the total scale of time. While a similar eruption is impossible within our lifetimes, it will happen again many times in the future.

      Now consider that the sun is going to run out of hydrogen in ~4.7-5b years and realize that we’re about halfway through this planet’s lifecycle.

        Won’t actually run out of hydrogen. Only the accessible bit in the core. Most of the hydrogen is in the outer layers and remains untouched. Thus why red dwarfs flare like crazy but Sol, a G-type star does not. Still, we only have around a billion years at Earth’s present orbit until the sun is hot enough that the seas will evaporate. That won’t matter after we live in space stations.
