Caged Bird

Where did this start?

I don't know why I was born
or the eternity this planet has been alive.
Confused where these creatures all came from
and where they might go.
Who can tell me the stories I wonder about so much.
Until that time comes, the doubt will never leave.
Never can I be sure
never can I fully understand,
all I can do is move on
Like everything isn't a question.
