Or you could try an honest appraisal of what we have plainly said. We do not redefine anything. We simply suggest that it is reasonable to call the lightening and darkening of the Earth's sky under the three day reign of God's first light evening and morning.
You think that only the sun can achieve this. No redefining, just an extraordinary lack of grace and humility on your part.
All you need for evening and morning is a day. God separated the light from the darkness, and he called the light day. There was light on the first 3 days, therefore there was day. Evening and morning define the boundaries of that day. There was light shining from morning to evening and darkness from evening to morning. Sunlight does not define a day.
