What is the 1st form of origami ever made?

The first form of origami is believed to have originated in Japan during the Heian period (794-1185), although its roots can be traced back to ancient Chinese paper folding techniques. The earliest known examples of origami were simple folds used for ceremonial purposes, such as the folding of paper for Shinto rituals. Over time, origami evolved into an artistic practice, leading to the intricate designs we see today. The exact "first" origami piece is hard to pinpoint, as the art developed gradually over centuries.
