I should have done it from the sun.
It would appear that he believes that light rays emanating from the sun would be as good as parallel to each other regardless of where on earth we are talking about. But the way he asked the question was the problem because the opposite of 'parallel' is NOT 'a specific angle'. His question suggests that light rays from an object like the sun have an in built 'angle' between the rays, which is obviously NOT the case. The angle between lines from a point depends on two things, the distance from the point and the distance between the lines.
