Why isn't morning called beforenoon?

Think about it, how silly would it sound, going around saying Good Beforenoon instead of Good Morning, and try singing 'Beforenoon has broken', doesn't quite scan does it.

And should we change afternoon to 'Beforenight', or even night to 'The Time of Dark Beforenoon.

See the link below, for explanation of the Word morning, instead of my silly answer above. The lighter side Sunny beforenight by the Kinks Lazy beforenight by The Small Faces Brand New Afternight by Magnum Would also sound strange. Him above started this so don't blame me blame him.
