These two girls live in a house that was at one point, converted into a church. But after the missionaries had left, it was turned back into their house. The girls don't understand why their house had to become the church, and their parents were not available to answer the question.
(As a side note... this deep in the jungle, most of the people do not speak Spanish. So our photography team worked with one translator who translated to Spanish, and that guy then translated into the indigenous language.)
This photographer has no inclination for or against church missions and is simply reporting the events as they were presented by the people who were available to tell the story.
