Somebody around here has never checked their concordance nor has performed a word study on the various ways on how yom is translated in the Bible....
See my post 99 if you need a little help.
I presume you made a typo when you said that a yom is from sunset to sunrise. If it wasn't a typo, then why do the Young-Earthers insist, without any grammatical basis, that yom has to mean a literal, 24-hour day -- except where it doesn't?
I referenced my knowledge of ancient and modern Hebrew - not a concordance written by a WASP. As for sunrise to sunset, that my friend is quite literally the biblical definition of yom. Please provide biblical proof of ANY other definition of yom.
