The fact you thought the Earth even might POSSIBLY be flat,

is PROOF POSITIVE: can ONLY MEAN

no one has EVER explained how longitude and latitude

are derived,

and used,

to predict on the surface of the planet.

IF YOU'D HAVE EVER BEEN TAUGHT THAT,

you'd know there can ONLY be ONE reason

ANY set of FORMULAS can PREDICT surface areas

and surface point locations

on ANY GEOMETRIC FIGURE THAT EXISTS.

They belong to THE FAMILY of '

'SPHERICAL COORDINATES."

Because they can ONLY predict,

on a SPHERICAL OBJECT.

fhe FACT the PLANET'S SURFACE AREAS

and

SURFACE POINTS,

can ONLY BE SUCCESSFULLY PREDICTED by THEM,

and YOUR NOT KNOWING WHY this MATHEMATICAL FACT exists,

is PROOF POSITIVE your EDUCATIONAL GRASP,

is SUB 12-YEAR-OLD.

12 YEAR OLDS and 14 YEAR-OLDS,

ROUTINELY TEACH THEMSELVES these MATHEMATICAL PREDICTION REALITIES and learn to sail and fly.

YOU will NEVER ESCAPE what NOT UNDERSTANDING HOW they WORK to PREDICT,

means for your N.O.N. E.X.I.S.T.A.N.T.

NON-GRASP,

of FUNDAMENTALS of HOW SURFACE AREA MATHEMATICS WORK.

You believe the Earth's flat or even might POSSIBLY be,

which can ONLY MEAN no one has EVER explained how longitude and latitude are derived to you

If they had you'd know there can ONLY be ONE reason ANY set of FORMULAS can PREDICT surface areas and surface point locations on the planet's SPHERICAL surface.

They belong to THE FAMILY of ''SPHERICAL COORDINATES."

Because the planet's surface can ONLY be predicted by COORDINATES derived FROM and FOR a SPHERE.

You will NEVER escape it..
