Was astronomy relied thousands of years ago, especially when cloudy weather obstructed visual observation?
Thousands of years ago, astronomy was not this accurate. But then there were not many man-made objects in the sky either. Now a days people can see many man-made objects and think they saw the moon. We are trying to educate the people, so they understand the basic known facts about the moon, and when is impossible to see, such that when a Muslim or group of Muslims see something and believe it to be the moon, we all can differentiate that it was not the moon; they have seen something else.
