The ground for this claim is that two of the stones determine a line pointing directly to the position of the sun at sunrise at the spring equinox. There are many stones in the ring, however, so the chance that one pair will point in a celestially significant direction is large. Therefore, the people who built the ring were not knowledgeable about celestial events.

IMO the flaw is: Lack of evidence is taken to prove a situation. However, lack of evidence may weaken/strenghten the situation, but may not be considered prove situation.

With that background, lets ponder the stimulus.

Just because one of the stones point in a celestially significant direction is large cannot be taken to prove something about the knowledge of people.
