An introduction to the vastness of geological time. I live by the Solway, between England and Scotland, once either side of the Iapetus Ocean.
My calculation gives humans appearing at 39.998 seconds.
That is the last 0.012 seconds.
At some point soon I will publish timeline calculators you can apply to a walk to measure human life against geological time. It makes geological vs human timescales physically perceptible.
