what does it mean to be alive?And in the vast infinity of time,how do I matter?Who am

Wow!
Those are questions profound and philosophical,
but I only know some about humans that are pedagogical.
May I try to find some answers for you,
and I may learn some from them,too.
To be alive is to become and to be
Tis' true for all the world,you and me
Limited is one's life,limitless is the time
But everyone has his or her prime.
What matters to you may not matter to others
since many do not have sisters or brothers.
Who am has been a century-long question,
that made philosophers sick in their digestion.
You are what you are and what you want to be
to become what you are and you are not me.
Let you be you and me be me,
in a world of infinity,we all shall and will be.
Good luck.
