The answer to this riddle is "Eternity".

“Eternity” is described as being nothing and everything because it is intangible and abstract, yet it encompasses everything that exists.

It states that it can be seen in darkness but not in light because eternity, as a concept, is often associated with the infinite and timeless nature beyond the physical realm, which is better perceived in darkness or introspection rather than in the brightness of the material world.
