I am seen in darkness and in light,
Can see it in the day sometimes, most of the time at night
I am calm yet tend to fright.
The moon is a symbol of peacefulness, yet it is also quite spooky when framed in such a way (think werewolves)
I can be quiet, I can be loud,
quiet / loud can be terms for how bright an object it. And the moon can be barely visible during the day (quiet), and in contrast to the night sky, very bright (loud)
I hide in shame, yet am so proud.
the moon hides behind the earth half sometimes
I can be different, but still the same,
different phases of the moon make it look different, but the moon itself never changes.
I am straightforward yet am playing games.
not really sure about this
you can easily find me,
but you'd have to look and see.
I am found everywhere I know,
if the moon was alive, it would know itself as a world/planet ('world' is sometimes used in language as a synonym for 'all' ex: "you mean the world to me" / "You mean everything to me") and so it would be found everywhere it looks.
but why is it sometimes not so?
because of the orbit of the moon, it is hidden from us sometimes behind the earth
So many things that I can make,
the moon makes the oceans tidal, it makes a great piece of art
but how many tries will it take?
this could be a reference to how many times it took to get to the moon
