My precocious 7 year old grandbaby has an inquisitive mind and hit me with the age old question.
Why am I here?
And she meant it in the entire philosophical sense.
Wow, you better start reading Plato and Aristotle and all sorts of philosophical texts to get out ahead of this child!
Great question from your granddaughter that's one of the two great philosophical questions throughout all history. (The other is how did I get here?)
So from the big picture standpoint there are only three major Worldviews and each answers; "Why am I here? quite differently.
1. Atheism answers that humans are a product of chance in a closed universe. We exist to reproduce.
2. Pantheism answers that like all existence, humanity is a manifestation of God. God is all things and all things are God.
3. Monotheism answers the humanity was uniquely created by God, distinct from all other creation and that human life is sacred.
I think that's what she's asking... the big picture question.
If she's asking more along the lines of "What is my place in the universe?"
1. Atheists answers that humans have no true freedom and that determinism (if evolution makes it so) plops humanity in an absurd universe where freedom is actually meaningless.
2. Pantheists answer that everything is God and that individuality is only an illusion.
3. Monotheists divide as to Islam's fatalistic determinism ("If God wills) or Christianity, where the unity of the Trinity signifies unity yet diversity and that every human has real meaning before a Triune God.

Best of luck in this conversation grandpa.
