The reconstruction of the total past of humanity is unattainable because "we only have fragments of the evidence."
This implies that in trying to reconstruct history or the past, we usually don't have the full evidence or pieces to reconstruct the past.
For instance, archeologists may find the foundation of an ancient temple, the rubbles of ancient forts, etc.
However, while we may try to reconstruct the full temple of old or full forts structure of old, we can't fully get it right because we don't know exactly what it looks like.
We can only make hypothetical images of those ancient structures, towns, or cities.
Hence, in this case, it is concluded that "the reconstruction of the total past of humanity is unattainable because we only have fragments of the evidence."
