Yes Master_Bob - you are right - the WT does not teach that the universe, including the Earth, was created as part of the creative days. My post did not mean to intimate that but on re-reading it through I can see that it does. To be fair, they also do mention that the age of the earth could be billions of years old in the Insight book.
Regardless, my point was that the WT uses very vague language to describe the length of the creative days which allows for a wide range of opinions which can easily lead to conflict with the scientific consensus. They can present a public persona of "the Bible and ourselves do not contradict science" whilst allowing individual members to hold completely nonsensical views.
