Since St.Nicholas was an actual person/Saint, would that make Santa Claus Real?

santa clause is real. no matter what. and i have so much evidence once i heard something in the chimney christmas eve and i started freaking out! and also i saw him in the sky once on xmas eve i was at the cemetary i saw rudolphs red nose and all there shadows! never question his belief... also my cousin heard him on the roof once on christmas eve.
