day and night were on day one, but the source of the light was NOT the Sun, which was not created until day 4.

It is very obvious that you are incorrect. Unless you think that God created light twice. Book 01 Genesis
001:001 In the beginning God created the heaven and the earth.
001:002 And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
001:003 And God said, Let there be light: and there was light.
001:004 And God saw the light, that it was good: and God divided the light from the darkness.
001:005 And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.
001:006 And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.
001:007 And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so.
001:008 And God called the firmament Heaven. And the evening and the morning were the second day.
001:009 And God said, Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so.
001:010 And God called the dry land Earth; and the gathering together of the waters called he Seas: and God saw that it was good.
001:011 And God said, Let the earth bring forth grass, the herb yielding seed, and the fruit tree yielding fruit after his kind, whose seed is in itself, upon the earth: and it was so.
001:012 And the earth brought forth grass, and herb yielding seed after his kind, and the tree yielding fruit, whose seed was in itself, after his kind: and God saw that it was good.
001:013 And the evening and the morning were the third day.
001:014 And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years:
001:015 And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so.
001:016 And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.
001:017 And God set them in the firmament of the heaven to give light upon the earth,
001:018 And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.
001:019 And the evening and the morning were the fourth day.
