You were made to know God.
People wonder about their purpose until God reveals Himself to them. When you encounter God and see Him for all He is, you realize that He is why you exist. He created you, so that you could know Him. Life has meaning beyond meager living; you are God's child.
If you are sensing some inkling that there is Something more to this life than what is in front of you, some draw to God, then I encourage you to take three simple steps in accordance with that draw: Experience Jesus. Trust Jesus. Follow Jesus.
Trust Jesus. Believe that He died to pay the penalty for everything you ever did wrong and declare Him the Lord of your life (Romans 10:9). Sin separated you from God, but Jesus made a way back. Trust Jesus.
Connect with God and become more and more like Jesus. Love God with all of your heart, soul, mind, and strength and love people like you love yourself (Mark 12:30-31). Pray, witness, and disciple. Follow Jesus.
