The last word of the last chapter.
Reason: modern humans (~200,000 yrs) vs. Earth’s age (~4.5 billion yrs) is about 200,000 / 4,500,000,000 ≈ 4.4×10^-5 of the whole. If a book were, say, 300 pages (~75,000 words at ~250 words/page), that fraction is only a few words — essentially the last word of the last chapter.
