Just my thoughts...
The evening came first because it was dark in the begining of Creation upon the earth:
Before God began creating on earth it was dark - like evening.
Then He made light - and so dawned the morning of day one, but since the world was already in existence in the preceeding darkness, the light morning couldn't be called the begining of the first day.
Morning and light thus came simultanously as God's first creative act on the newly formed earth, but in recognition that the earth already existed in the darkness preceeding that, God says the day had already started back then, in the evening darekness.
So... there was evening darkness and then there was morning light, and the day carried on until 24 hours later evening fell and that was day two begining.
The rest of the days then had to follow that pattern, and therefore the Jewish people still start their days on what we call the evening before.
(Just my thoughts, hard to explain and I went on a bit, hope it makes sense. I've no idea if that's right, just seems to make sense to me!)
and if this is all true and if we are now in the end times we would be in the TWILIGHT time of the whole of scripture
RIGHT ??
Ooh, now that's making me think...
