The rosary is a meditation prayer. You reflect on the life of Our Lord as you repeat the angel Gabriel’s greeting to Mary. “Hail! Full of Grace”. Truly beautiful and a powerful prayer against the powers of evil. The Our Father is of course the prayer Jesus taught to us. Your comments seem dismissive of these two facts from the Bible.
Why are you praying to Mary? Nothing Biblical about that. In fact, it's contrary to the Bible. Pray to God directly, or through Jesus, but not through Mary.
