The Mystery of Ancient eclipses

"The calculated location of the ancient solar eclipses could have an error of up to about 10 kilometers." This statement by the U. S. Space Administration NASA is a scientific outstretching of how ancient eclipses can be found. When numerous eclipses observed in ancient times are applied to that measure set by science, they reveal a very significant secret of ancient history. Another significant factor is the lunar eclipses of the ancient Ur III dynasty.
Can they be found? And what does everything have to be considered in order to find them? Why haven't scientists discovered the double eclipse of Babylon?
