Humanism is not science, but religion - the post-Christian faith that humans can make a world better than any in which they have so far lived. In pre-Christian Europe is was taken for granted that the future would be like the past. Knowledge and invention might advance, but ethics would remain much the same. History was a series of cycles, with no overall meaning.
Against this pagan view, Christians understood history as a story of sin and redemption. Humanism is the transformation of this Christian doctrine of salvation into a project of universal human emancipation. The idea of progress is a secular version of the Christian belief in providence. That is why among the ancient pagans it was unknown.
