Yom is the Hebrew word for day. If you will look at the first several verses of Genesis 2 you will find the key to translating the meaning of yom in Genesis 1 (The first several verses of 2 are a continuation of Genesis 1. The chapters were done without regard to completed passages.
It is clear that yom means an indefinite period of time. This is in conformance for God's using evolution to provide a changing life to a changing environment.
With all due respect, you have demonstrated a remarkable ignorance of Hebrew grammar. You may be able to find a dictionary a cherry pick a definition from it, but that is a common fraud that evolutionists use to bully creationists.
Any time "yom" is used with a number, it always means a regular day. Anytime "yom" is used in conjuction with the word "morning", it means a regular day. Everytime "yom" is used in relation to "evening" it means a regular day. So can you take a wild guess as to what rule of grammar applies when the word "yom" appears with (1) a number, (2) morning and (3) evening as it repeatedly does in Genesis, Exodus and Deuteronomy?
Also, it appears that you are unwilling to answer the doctrinal question regarding the appearance of death in the Creation in relation to Adam. Your original post was quite insulting and immflamatory in that you categorically called Christians who reject atheistic evolution as unbelievers. Yet you can't seem to grasp how evolution attacks the very core of the gospel message.
Another question for you, not doctrinal, but indicative of your attitude towards the veracity of the Scriptures: Given that the Global Flood is described in the Genesis narrative, and the flood is declared by God to be sent to destroy all "that breathes" (save those aboard the ark), wouldn't that same catastrophy also destroy all of that so-called evidence prior to the antediluvians?
Take your time... :)
