JW never thaught that was done in six literal days. It was actually six days of 7000 years each.
This is interesting.
The "each creative day lasted exactly 7000 years" idea has not appeared in print for over 30 years. It was taught in Gilead classes as recently as 15 years ago, but in any event, it is not at all a current JW teaching. They are now purposely vague about each day's length, and I've even seen printed references accepting the age of the universe as 13-14 billion years.
So our new poster seems to be an "old school" JW, or at least was raised by old school JW parents.
