The video starts out "God wrote a book long before man knew how to write." In fact it has been in publication for billions of years and only the newer editions mention human beings.
Since man came along, a lot of books about the 'meaning of life,' written in man-made languages, have come along. This one is a popular one. This copy was given to me in 1957 by the church my family regularly attended in Wilmington, DE. I've read it cover to cover once and am working on a second reading.
But it's a pale reflection of the better, much more complete book. Watch and listen (not necessarily to this video, but when you're taking a walk out in the forest,) to see what I mean.
