However, human beings love to see factual precision, and we want to know how old something is.
Shai Cherry of Vanderbilt University notes that modern Jewish theologians have generally rejected such literal interpretations of the written text, and that even Jewish commentators who oppose some aspects of science generally accept scientific evidence that the Earth is much older.
Many of the earliest Christians who followed the Septuagint calculated the date of creation to be around 5500 BC, and Christians up to the Middle Ages continued to use this rough estimate: Clement of Alexandria (5592 BC), Sextus Julius Africanus (5501 BC), Eusebius (5228 BC), Jerome (5199 BC) Hippolytus of Rome (5500 BC), Theophilus of Antioch (5529 BC), Sulpicius Severus (5469 BC), Isidore of Seville (5336 BC), Panodorus of Alexandria (5493 BC), Maximus the Confessor (5493 BC), George Syncellus (5492 BC) and Gregory of Tours (5500 BC).
The atom's atomic mass number stays the same because the total number of protons and neutrons remain the same. Biostratigraphic zone unit of geologic time defined by the presence of one or more fossil species.
Interval zones use the range of single species, assemblage zones use the ranges of a group of species, while abundance zones use maximum or minimum abundances instead of just presence and absence data. The third and current (most recent) geologic era of the Phanerozoic Eon, which began 65.5 million years ago; colloquially referred to the "Age of Mammals".
Mammals and birds are the dominant vertebrates on land, teleost fish in the sea, and angiosperms (flowering plants) and in certain areas conifers the predominant form of plant life.
Closed system A system (rock, planet, etc.) which has no influence or exchange with the outside world.
Proposed calculations of the date of creation, using the Masoretic from the 10th century – 18th century include: Marianus Scotus (4192 BC), Maimonides (4058 BC), Henri Spondanus (4051 BC), Benedict Pereira (4021 BC), Louis Cappel (4005 BC), James Ussher (4004 BC), Augustin Calmet (4002 BC), Isaac Newton (4000 BC), Johannes Kepler (27 April, 3977 BC) [based on his book Mysterium], Petavius (3984 BC), Theodore Bibliander (3980 BC), Christen Sørensen Longomontanus (3966 BC), Melanchthon (3964 BC), Martin Luther (3961 BC), John Lightfoot (3960 BC), Cornelius Cornelii a Lapide (3951 BC) Joseph Justus Scaliger (3949 BC), Christoph Helvig (3947 BC), Gerardus Mercator (3928 BC), Matthieu Brouard (3927 BC), Benito Arias Montano (3849 BC), Andreas Helwig (3836 BC), David Gans (3761 BC) and Gershom ben Judah (3754 BC).
Among the Masoretic creation estimates or calculations for the date of creation Ussher's specific chronology dating the creation to 4004 BC became the most accepted and popular, mainly because this specific date was attached to the King James Bible.
Dating is a science and discipline which requires extensive training.
