Is air present on moon!!how the flag is blowing....

Some scientists say that
there is no atmosphere
on the moon.
Some say that atmosphere is present but
oxygen is not present on moon.
What may be the fact,
but it is not possible to hoist a flag on moon
due to absence of atmosphere,
blowing wind and
relatively lower gravitational field.
It causes a doubt and it seems that
the photograph of Neil Armstrong
on moon
is a creation in a studio
with a black background.
Is it possible to take a photograph
without stones,rocks or anything in background
in a clear sunlight.
Note the sunlight is enough to create
shadows of Neil
and his machines and flag of U.S.A.
In fact nobody
was actually on that day
on moon
and this image is inviting a lot of doubts.
