Because Christ commanded us to at his last Passover with the Disciples.
It is commemorated in I Corinthians 11:23-26: (The Apostle Paul speak in the letter)
For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread, and when he had given thanks, he broke it and said, "This is my body, which is for you; do this in remembrance of me." In the same way, after supper he took the cup, saying, "This cup is the new covenant in my blood; do this, whenever you drink it, in remembrance of me." For whenever you eat this bread and drink this cup, you proclaim the Lord's death until he comes. (NIV)
It is a memoriam and a public profession.
The five main sections of the Mass are the Introductory Rites, Liturgy of the Word, Liturgy of the Eucharist, Communion Rite, and Concluding Rites. The Introductory Rites prepare the congregation for worship, while the Liturgy of the Word includes readings from Scripture and the homily. The Liturgy of the Eucharist focuses on the celebration of the Eucharist, followed by the Communion Rite where the faithful receive Communion. Finally, the Concluding Rites send the congregation forth to live out their faith.
After communion during a Catholic Mass, the concluding rites take place, which include a final blessing, prayers, and the dismissal of the congregation.

James wrote, The devils believe in God and tremble. Believing in God does not save one. Accepting Jesus, the son of God and propitiation for your sin saves you and until that happens, it does not really matter what rites you observe. Communion means to commune with God. If you believe in God, then you are already communing with Him. Therefore, you don't need the paganistic ritual of eating the flesh and blood of JC (communion rites).
