Factual error: Young David focuses his telescope at the moon. A close up shot then shows a circular view i.e. it is supposed to be the view through the telescope. Both the moon and the clouds in focus. With a telescope the depth of field is short and, with the moon in focus, the clouds would actually be blurred.

Mary Luckett: Well I for one don't believe any of this alien crap.
Alma Finley: You mean you don't believe your husband?
Mary Luckett: No, I don't believe him.
Alma Finley: Well I believe him and I'm scared.
