Whether they slept or not, Earthlings always needed the external light difference between day and night.
Different sunlight would have subtle effects on human brain thinking, allowing the relatively unstable quantum thinking of humanity to rest and relax after high-speed operation.
The human brain quantum thinking framework, composed of countless small and large spirals, was a complex "pseudo-machine".
