I mostly love this show, but there have been way too many episodes treating religion as equal to all other fields. At the risk of being sarcastic, to the best of our knowledge, faith and belief in gods is belief without evidence. Is faith "knowledge," or is it superstition?
The subject of religion is all well and good, but a show that treats religious faith as knowledge, instead of what it is - an irrational belief system, undermines the credibility of this program.
PLEASE stop passing these people off as contributors to what is considered the "best" of our knowledge. Why not have more shows that treat astrology as legitimate knowledge? If that sounds absurd, then you get my point.
