Superstitions magic and miracles

I was thinking about how society has thankfully progressed  and we stopped believing in superficial nonsense.What was it that kept ppl in the dark?They were afraid of the lighting bolt or thought Zeus was angry. Is it our nature to fear the unknown? Could be...
But then again during the medieval ages everyone was considered a witch especially women that showed any sign of being interested in sciences or any form of education...So is it that we use fear or superstitions to suppress others?Or pass our own agenda. Are today's ppl demonized when they are different or have different beliefs, does society try to ostracize them ?But what is it, is it the unknown or the new? do we feel unsafe or unsure ? Possibly we need something greater than us to believe in so we have someone to blame for our mistakes lol. It was the new and controversial that progressed science so far though many scientists in their time were considered "crazy" with baseless theories or would have been considered witches in their day if they were open about their research. Maybe it's more convenient to be "naive" as we are for so many subjects.
So Let's bless ourselves with this holy CD
