James Ussher, an Irish archbishop and scholar, calculated the date of creation based on the genealogies listed in the Bible. According to his calculations, he concluded that the Earth was created on October 23rd, 4004 BC. This calculation was made in the 17th century and is not accepted as a scientifically accurate estimate of the age of the Earth. It is important to note that the age of the Earth has been determined to be around 4.54 billion years old based on a range of scientific evidence and dating techniques.
