The Lord's Prayer Is Not Jesus's Prayer
The prayer Jesus taught his disciples was not how he prayed — John 17 shows how he prayed.
Matthew 6:9–13 and Luke 11:2–4 give the Lord's Prayer in response to 'teach us to pray.' It is explicitly a template for disciples. John 17 records an actual prayer of Jesus — 26 verses, addressed to the Father, about the disciples, about glory, about unity, and about the future. The Lord's Prayer contains 'Our Father' and petitions for daily bread and forgiveness. Jesus's actual prayer in John 17 contains no petition for daily bread and no request for forgiveness. The content is almost entirely about others and about completing the work he was given. The two prayers are structurally distinct: one is a disciple template, one is an extended intercessory prayer.

Matthew 6:9John 17:1John 17:20
After this manner therefore pray ye: Our Father which art in heaven, Hallowed be thy name.
These words spake Jesus, and lifted up his eyes to heaven, and said, Father, the hour is come; glorify thy Son, that thy Son also may glorify thee:
Neither pray I for these alone, but for them also which shall believe on me through their word;
Evidence Notes
Matthew 6:9 is framed as 'After this manner therefore pray ye.' John 17 is Jesus's own prayer with no daily bread petition.
