Imagine Jesus was out with the apostles one day, and it's raining incredibly hard. Jesus says something like 'it's raining cats and dogs!' After the crucifixion, Peter remembers this, and creates the Rite of Canine and Feline Precipitation. 

That's basically what happened. During the Last Supper, Jesus was illustrating the importance of the word of God. When Jesus pointed, Peter consistently made the mistake of looking at the finger instead of at what was being pointed at.

This is just conjecture on your part

To some extent yes, but it's mostly from reading all the other Christian texts Peter's church rejected, including his own portrayal in them.

You mean gnostic bullshit don't you

Ie the truth. :D

'Gnostic' is a label like 'anti-vaxxer' or conspiracy theorist.
