Well, certainly, the whole purpose of it is to bring up those questions. Our existence is a big question mark, that's the whole point!
Our Creator has given us a handbook for life that explains our origins and purpose. The Creator of life has given us the Bible, which is composed of law, historical information, poetry, prophecy, and divinely inspired letters that explain our role in the universe. The Apostle Paul writes:
"For by him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things were created by him and for him" (Colossians 1:16).
This explains our origins, and to some extent the reason for our origins. Fortunately, we have been told the nature of our Creator, to further help us answer the question "Why do we exist."
"Whoever does not love does not know God, because God is love" (1 John 4:8).
God is love. God is not subject to desires such as that for pleasure; His existence is beyond this. He did not create us for His own carnal desires; He created us for the proliferation or multiplication of love.
It is for this reason that the commandments are summed up in two decrees: "Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength…Love your neighbor as yourself. There is no commandment greater than these" (Mark 12:30-31).
God's commandments are merely a guide to how we should increase love - His love. "This is how we know that we love the children of God: by loving God and carrying out his commands" (1 John 5:2).
The purpose of our life is to love God, and therefore to keep His commandments, because He created us for love.
