So... according to the WTS, Adam was created a little over 6,000 years ago. After being created he was given the task of naming all the animals. Then Eve was created, a talking snake got them to eat some fruit and the rest is history...
Anyway...
How long did it take Adam to name all the animals before the fairer sex was brought to him, undoubtedly distracting him from the heavenly chore set before him?
And...
Later in Genesis, Noah was tasked with building an ark, so as to preserve 8 humans and 2 (or 7, depending on which chapter you prefer to read) of each of the animals.
So...
How many of these ga-jillion critters was Noah able to fit on his boat, along with enough food/water for them all?
These are questions that beg to be asked after reading the "Watching the World" segment on "How Many Species on Earth"...
