Cecelia Ahern's book "The Gift" explores the idea of miracles and belief through the lens of chemistry. The quote suggests that if miracles were tangible and could be explained with scientific formulas, they would be universally accepted and understood. This points to a desire for empirical proof in a world often guided by skepticism regarding extraordinary experiences.

The emphasis on a chemical equation reflects humanity's quest for certainty and rationality. Ahern's thematic exploration encourages readers to consider what it means to believe in the extraordinary without relying on physical evidence, highlighting the tension between science and faith in our understanding of life's wonders.
