While it would obviously help refute my question, if Paul did meet and spend days with Jesus it is not really important to addressing the problem. Paul himself never states that he met anyone who knew jesus either personally or perhaps was lucky and ran into him during his ministry.
As ialready states the last supper is not unique to Jesus, it also existed in many other religions. I forgot to include Judaism also has a last supper event called the passover. We could summary the passover to just bread and wine as symbols.

3 May YOU people have undeserved kindness and peace from God our Father and [the] Lord Jesus Christ.
4 I always thank my God when I make mention of you in my prayers, 5 as I keep hearing of your love and faith which you have toward the Lord Jesus and toward all the holy ones; 6 in order that the sharing of your faith may go into action by your acknowledging of every good thing among us as related to Christ. 7 For I got much joy and comfort over your love, because the tender affections of the holy ones have been refreshed through you, brother.
8 For this very reason, though I have great freeness of speech in connection with Christ to order you to do what is proper, 9 I am exhorting you rather on the basis of love, seeing that I am such as I am, Paul an aged man, yes, now also a prisoner for the sake of Christ Jesus; 10 I am exhorting you concerning my child, to whom I became a father while in my [prison] bonds, O·nes´i·mus, 11 formerly useless to you but now useful to you and to me. 12 This very one I am sending back to you, yes, him, that is, my own tender affections.
This is hardly proof, its just the name. It does not show the author actually was aware of Jesus or his ministry. This is important as fraudulent letters were a real problem and there are many scholars that have commented that at key spots some new words were inserted into scripture.
