You're extremely ignorant of not only scripture and exegeting verses,
but are totally in the dark regarding the history of the church.
Again,,,PETER was the leader of the Apostles:
He is the leader of the Apostles as represented in the NT.
1. Jesus gives the keys....the AUTHORITY...to Peter and NOT to the other Apostles. There could only be ONE leader.
Matthew 16:19
19“I will give you the keys of the kingdom of heaven; and whatever you bind on earth shall have been bound in heaven, and whatever you loose on earth shall have been loosed in heaven.”
2. Jesus tells Peter to tend to, and shepherd His sheep.
John 21:15-17
15So when they had finished breakfast, Jesus said to Simon Peter, “Simon, son of John, do you love Me more than these?” He said to Him, “Yes, Lord; You know that I love You.” He said to him, “Tend My lambs.”
16He said to him again a second time, “Simon, son of John, do you love Me?” He said to Him, “Yes, Lord; You know that I love You.” He said to him, “Shepherd My sheep.”
17He said to him the third time, “Simon, son of John, do you love Me?” Peter was grieved because He said to him the third time, “Do you love Me?” And he said to Him, “Lord, You know all things; You know that I love You.” Jesus said to him, “Tend My sheep.
3. John shows respect/deference to Peter as he was the elder of the Apostles.
John 20:3-5
3So Peter and the other disciple went forth, and they were going to the tomb.
4The two were running together; and the other disciple ran ahead faster than Peter and came to the tomb first;
5and stooping and looking in, he saw the linen wrappings lying there; but he did not go in.
6And so Simon Peter also came, following him, and entered the tomb;
4. Peter was the first to speak at the gathering of the Apostles - and for the picking of Matthias to replace Judas.
Acts 1:15.....
15At this time Peter stood up in the midst of the brethren (a gathering of about one hundred and twenty persons was there together), and said,
16“Brethren, the Scripture had to be fulfilled, which the Holy Spirit foretold by the mouth of David concerning Judas, who became a guide to those who arrested Jesus.
17“For he was counted among us and received his share in this ministry.”
18(Now this man acquired a field with the price of his wickedness, and falling headlong, he burst open in the middle and all his intestines gushed out.
19And it became known to all who were living in Jerusalem; so that in their own language that field was called Hakeldama, that is, Field of Blood.)
etc.
5. Peter spoke for the Apostles at the Jewish Religious Court.
Acts 4:6-9
6and Annas the high priest was there, and Caiaphas and John and Alexander, and all who were of high-priestly descent.
7When they had placed them in the center, they began to inquire, “By what power, or in what name, have you done this?”
8Then Peter, filled with the Holy Spirit, said to them, “Rulers and elders of the people,
9if we are on trial today for a benefit done to a sick man, as to how this man has been made well,
etc.
There's more but this should suffice.
To say nothing of the fact that
Peter was the leader of the church in Rome; one of the 5 important areas of the time.
This is easy to learn of if one is interested:
