Humans suck at comprehending very large numbers. Studies have shown that most people cannot grasp the enormity of scale between one thousand, one million, and one billion. When asked, they will wildly misjudge the halfway points between each because they lack a comparative frame of reference. It’s because our minds are hardwired to try and compare conceptual ideas to some kind of physical reference point or dataset.
We can easily visualize a hundred of something. A thousand is more difficult but doable. Getting into the millions and billions though and none of us have ever observed any grouping of anything at that scale. Gigantic numbers can only exist in conceptual form.
