Primitive Tools found near Microsoft Headquarters ...

Could it be the abandoned tools of the ancient's
first attempts at the precursor to today's Windows
Operating System ???
Though glass was not yet invented, pieces of nacre
found strewn throughout the site indicate that the
ancients attempted to use polished Abalone Shells
for the translucent Windows Logo of their first HnS
(Hunt 'n Stab) "Cave Entrance 10BC Operating
System":

But alas, even though glass has long since been
invented and code has moved from chiseled stone
steles to desktop PCs, that old three-finger-
salute (ALT-CTRL-DEL) is still with us today,
reminding us of who really invented that forever
bug-ridden, obese monster called "Windows".
