Let's start with a simpler example:  The concept of 'dinosaur' did notexist before the 19th century, but when we find a dinosaur bone we sayit is, for instance, 200 million years old.  Does it make sense to saythere were no dinsaurs before 200 years ago, but their bones are 200million years old?Before Newton the moon revolved around the earth & the earth aroundthe sun--were these motions in accordance with the law of gravity?Yes, because we can find observations of eclipses by astronomersbefore Newton & we can retrodict those eclipses.Craig
