It wasn't because even today no one has ever discovered the exact value of pi and all we know is that its value is that of a circle's circumference divided by its diameter which is an irrational number.
Pi was discovered ny the ancient Greeks around 1900 B.C

Pi wasn't invented so much as discovered. Pi is the ratio of a circle's circumference divided by the diameter. One could say that no one invented it, but that it was discovered. The Egyptians and the Greeks had an a approximation that we are still refining to this day. It is a transcendental (non-rational) number.
Because the Greeks discovered the fact that the radius and circumference of a circle maintained a constant ratio.
