Did Americans Really Land on the moon

It is said that Niel Armstrong landed on the moon first...But it is now said that the Americans never landed on the moon first, It was shot as a picture on the American Studio, Because the shadows prove that there was many light source and also the flag would be waiving but there is no chance of flag to waive in moon as there is no air in the lunar space..... Who knows may be it is true..... Then it is a shame for America
