you must think that the sun's rays are parallel and never touching, therefore all create the same angle.

Geochronology is the method of determining the absolute age of rocks, using radiometric methods.

No, that calculation was performed by Eratosthenes the Greek, as he worked in the Pharaoh's library at Alexandria, Egypt, using figures supplied by the Pharaoh's geometers. This would have been just a few centuries after the founding of the City of Rome, before it had grown into an empire. Eratosthenes worked out the method for determining earth's circumference after reading ancient Egyptian texts concerning the shadow cast in a well in Cyene, an Egyptian city on the Tropic of Cancer, at noon on the summer solstice.
About 276 BC Eratosthenes was a Greek mathematician who is credited with a simple method of making a list of as many primes as you wish. His method is known as the Sieve of Eratosthenes.
Eratosthenes' method of finding prime and composite number is called 'The Sieve of Eratosthene'.
He was an ancient Greek mathematician of the 2nd/3rd century BC, as well as a poet, geographer, musical composer, scholar, and astronomer. He was the first Greek to estimate the circumference and tilt of the earth. He created a map of the earth based on the knowledge available at the time. He was highly respected, and his calculations of the earth's circumference were used for hundreds of years. Today, his method for finding prime numbers from 1-100 is known as the 'Sieve of Eratosthenes' and is taught in math textbooks.
It is called a sieve.

Eratosthenes created a sieve that will do that.
Eratosthenes' method requires that one know or determine the vertical angle of the sun above the horizon or from the zenith (a point directly overhead) at solar noon at two locations along the same line of longitude. The distance between the two locations must also be known.
