I’d guess it pretty closely follows the development of concepts that put words to spacial dimensions - 2 points make a line, 2 lines make a plane, multiple planes establish a volume, etc
If you think of time as a line and follow the same logic as spacial dimensions, you have the ‘line’ that represents reality as you’ve experienced it, but every event that has more than one potential outcome branches out from that point the same way the axes that make up length, width, and depth branch from one point. Instead of a 3-D space, we have… well, the multi-worlds theory.
