Creating a very long timeline

Following this answer (https://tex.stackexchange.com/a/472967/211164), I’m trying to create a historic timeline ranging from 200,000 BCE to 2020 CE, but seemingly ran out of page space: "Dimension too large."

How can I extend the dimension to fit my timeline onto a sheet of paper? Alternatively, would it be easier to go vertical?

Note: this is a condensed version as the actual version features many more date inputs.
