....and by these were the nations divided in the earth after the flood.
Genesis 10:32
"A cuneiform tablet, thought to be around 3,700 years old, and
designated Si.427 is now said to be the oldest example of applied
Pythagorean geometry.
The clay tablet from Babylonia was unearthed in
central Iraq in the 
late 1800s, and displayed in the Istanbul
Archaeological Museum, Turkey, for more than a century.
Daniel Mansfield, a mathematician from Australia’s University of New
South Wales (UNSW), gained access to the tablet, and recognized its
significance.
Mansfield had published about a similar tablet, Plimpton
322, which he determined was the oldest known trigonometric table. It
shows that “the Babylonians had an advanced knowledge of mathematics and
[that] Pythagoras’ theorem was known a thousand years before
Pythagoras.”
**The tablet is now thought to be a surveyor’s plan of a field which
ses trigonometry to work out the lengths and areas of the land. It may
have been used in legal disputes, or to calculate the land’s crop yield.
The UNSW report says that Si.427 “reveals that mathematics during this
era was more sophisticated than previously assumed.”
---These findings are consistent with the history in Genesis—humans were
created intelligent from the beginning—rather than evolutionary ideas
of human progress from primitive ancestors. ---Since Babylon was in the
region civilization recommenced after Noah’s Flood, we would expect to
see sophistication here from the very earliest times." CMI
