"The researchers' method even dates the fork points in their language tree, although the dates have a wide range of possibility. The initial splitting of Indo-European in Europe occurred around 8100 B.C., give or take 1,900 years, and the divergence between the continental and British versions of Gaelic took place in 3200 B.C., plus or minus 1,500 years, they calculate."
The oldest paper ever found (in China) had Tocharian written on it. Tocharian A & B is an extinct Indo-European language that is related closest to ancient Celtic. (Source: Professor Victor Mair)
