Query: Fascinating and informative

We purchased this series for our upper elementary aged son. He had been learning about space in school and his interest was sparked. He really enjoyed this series. I also found the series fascinating. I have watched most of the series and plan to watch the rest when they are returned to us. (He lent them to his teacher.) The theories presented regarding distant starlight, the uniqueness of the sun as a star, and the improbability of finding life in outer space are thought provoking and Biblical. In my opinion, this series is appropriate for upper elementary through adult age groups. Although our son does not completely understand all the information presented, there are enough rocket and space pictures to keep him interested. He will grow into the rest of the information.
