I have stated a fact. You cannot refute it. My position stands.<quoted text>
Cling to your archaic notions of reality all you want. I find your illogic extremely disturbing. And I refuse to agree with such foolishness. In logic, begging the question is a type of fallacy occurring in deductive reasoning in which the proposition to be proved is assumed implicitly or explicitly in one of the premises. In other words your proposition that on the day you were born, your age was 0, is based on the premise that age begins at birth, which is an assumption that has no scientific merit, and serves no beneficial purpose.
Our existence does not begin with birth. Our existence begins with fertilization. Age begins with existence, and nothing else. An infants gestational age is never 0, an infants calendar age is never 0. Age is only 0 at the beginning of existence, and our existence begins with fertilization. The gestational age, as does the calendar of infants varies with each individual. A premature baby is an infant of less than 37 weeks gestational age on the day the baby is born. The earliest gestational age at which the infant has at least a 50% chance of survival is referred to as the limit of viability. As NICU care has improved over the last 40 years, viability has reduced to infants approximately 24 weeks old on the day they are born, although rare survivors have been documented as early as 21 weeks old on the day they are born.
The gestational age of infants can be measured by looking at the infant's weight, length, head circumference, vital signs, reflexes, muscle tone, posture, and condition of the skin and hair. Or from the first day of the woman's last menstrual cycle before pregnancy to the current date. The infant's developmental gestational age may not be the same as the infants calendar age. For example, an infant 36 weeks old at birth may actually have a developmental gestational age of 38 weeks at birth.
Why is it important to determine gestational age of infants? Because gestational age is a rough estimate of or calendar age, that helps obstetricians and neonatologists anticipate what complications an infant might be expected to have. This can help them anticipate the infant's needs. Whereas determining age from birth is inaccurate, and serves no beneficial purpose in helping obstetricians and neonatologists anticipate what complications an infant might be expected to have. Birth is just an arbitrary point in our lifespan, and has nothing to do with determining our actual age.
Our age begins at birth, not before. On the day we are born, our age is 0.
