There doesn't seem to be stars because the sun light hitting the surface of the moon makes it super bright, therefore stars aren't very see able.
And if you say one thing about not being able to see the American flag, how can you? You'd need to use a high powered telescope for something so small.
Personally, I’m not really sure, but what could’ve made that flag wave? Please post your opinion.
EDIT: I am, of course, talking about that first moon landing of Neil Armstrong.
