VI. CONCLUSIONS
This paper investigated the meaning of creation “days.” It has considered key arguments in favor of a figurative, non-literal meaning of the creation “days.” It found them to be wanting on the basis of genre investigation, literary considerations, grammatical study, syntactical usages, and semantic connections. The cumulative evidence, based on comparative, literary, linguistic and other considerations, converges on every level, leading to the singular conclusion that the designation yôm, “day,” in Genesis 1 means consistently a literal 24-hour day.
The author of Genesis 1 could not have produced more comprehensive and all-inclusive ways to express the idea of a literal “day” than the ones that were chosen. There is a complete lack of indicators from prepositions, qualifying expressions, construct phrases, semantic-syntactical connections, and so on, on the basis of which the designation “day” in the creation week could be taken to be anything different than a regular 24-hour day. The combinations of the factors of articular usage, singular gender, semantic-syntactical constructions, time boundaries, and so on, corroborated by the divine promulgations in such Pentateuchal passages as Exodus 20:8-11 and Exodus 31:12-17, suggest uniquely and consistently that the creation “day” is meant to be literal, sequential, and chronological in nature.
The Bible is not literal in most passages. And you can’t expect anyone to take an argument seriously that is supported by the publication that you quoted.
