Why are some religious people afraid of the big bang?

I was at work today and was talking to my boss. He is a very religious man, in his off time he runs a ministry. We were just talking about normal everyday “stuff”, somehow we got onto TV shows and so he started telling me about TV shows that he watches and then I proceeded to tell him mine, which one turns out to be The Universe. He quickly jumped in and said “oh I don’t watch any of that stuff about “The Big Bang” and quickly changed the subject like he was frightened of it. I started thinking, why if he has so much faith can he not just at least watch shows/docus about that sort of thing. Is it because it may cast doubt in his mind about his faith and he would rather play it safe than sorry (in his mind)? Do they just think all that sort of “scientific mumbo jumbo” is false? I really want to ask him, but him being my boss I don’t think that is a debate I’d want to get into with him. therefore I just leave it alone.
