the gods are crazy

the "circle" is in fact the artifact of an ancient city
built by aliens the size of bugs,
for whom the stones were big as houses,
providing them with more than adequate protection
from the dinosaurs or other local threats to their survival.
in fact, their advanced technological skill
allowed them to construct the city in such a way
that it has survived all these millennia,
even through the great ice age,
when lake michigan
and all the other great lakes
were carved out by advancing glaciers.

the manual does have chapters as you imagine.
but was written by the ancients in their native tongue.
it isn't actually a "book" the way we think of a book,
but is more of a series of interconnecting beams of light
and other particle waves,
combined with various base elements
that one might find
in any decent hardware store
or hair salon.
I stumbled upon it one day,
while cleaning out my garage.
had forgotten about it for eons.
that certainly brought back some fond memories,
I can tell you.
