Is it true that genealogies in Luke and Matthew can help determine how long ago the creation event was?

The assertion that genealogies in Luke and Matthew can help determine how long ago the creation event was is false because the genealogies in these two Gospels primarily serve different theological and literary purposes rather than providing a precise chronological timeline for creation.

The genealogies trace the lineage of Jesus back to significant figures in Jewish history, emphasizing his connection to both David and Abraham, which holds particular importance for the narrative and theological intentions of each Gospel. The differences in names and the inclusion of different ancestors reveal varied emphases in the narrative—Matthew focuses on the Jewish context of Jesus, while Luke presents a more universal perspective by tracing Jesus’ lineage back to Adam.

Additionally, the genealogical records do not provide dates or specific timelines that can be directly correlated with the creation event. Instead, the genealogies illustrate the fulfillment of prophecy and the continuity of God's plan throughout human history, but they do not offer a means to calculate the timeline of creation. Therefore, the statement is accurately characterized as false based on the nature and function of these genealogical accounts within their respective texts.
