Among my favorite “proofs” is the fact that there was a birth announcement in the paper back then. All it really proves is something we all know; Grandparents post announcements of their grandchild’s birth.
My nieces and nephews were born all over the country but they all got birth announcements in the local paper. Sometimes those announcements indicated they were born elsewhere sometimes they didn’t.
It doesn’t mean there was a conspiracy to make baby Zero the president some day but it does come in handy for a family of dedicated communists who realize what they have later on.
The only sure thing here is that he could clear it up in an instant if he chose to do so.
So then, you agree that it's possible?
