According to Isaac Newton, the Earth was created in 3998 BC.
Newton, a renowned scientist of the 17th and 18th centuries, dedicated some of his efforts to calculating the age of the Earth based on biblical and historical sources. Like many of his contemporaries, he believed in a relatively young Earth, with a creation date determined by meticulously analyzing historical texts and genealogies. While he is best known for his contributions to physics and mathematics, his chronological studies reflect a common intellectual pursuit of the era. This differed greatly from modern scientific understanding, which, through radiometric dating and other techniques, places the age of the Earth at approximately 4.54 billion years. Newton's calculation highlights the prevailing worldview of his time, where religious and historical texts held significant authority in scientific matters.
