My question is : Do they still talk about 6,000 of human history ?
Yes.
Do they still talk about 7,000 years as a creative day ? "From paradise Lost To Paradise Regained " WTB&TS
No. They now ambiguously state that creation days can be 'many thousands of years'. This accommodates the old timers who still believe in 7000 years but at the same time allows the younger crowd to accept scientific evidence that plants and animals existed long before 49.000 years ago (of course they still ignore the evidence re the age of mankind). They're really masters of word crafting.
