2nd Day: Monday - Heaven God said, "Let there be a firmament in the midst of the waters, and let it divide the waters from the waters." Thus God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament; God called the firmament ( The expanse of the heavens or the sky ) Heaven. [Gen 1:6-8]
The Earth was already in existence on the 1st day, although without form and void. The Lord God did not cause it to rain on the earth, but a mist went up from the earth and watered the whole face of the ground. Before any plant of the field was in the earth and before any herb of the field had grown, and there was no man to till the ground. [Gen 2:4-6]
3rd Day: Tuesday - Continents / Oceans / Grass / Herbs / Trees God said, "Let the waters under the heavens be gathered together into one place, and let the dry land appear;" and God called the dry land Earth, and the gathering together of the waters He called seas. Then God said, "Let the earth bring forth grass, the herb that yields seed, and the fruit tree that yields fruit according to its kind, whose seed is in itself." [Gen 1:9-13]
4th Day: Wednesday - Sun / Moon / Stars
God said, "Let there be lights in the firmament of the heavens to divide the day from the night; and let them be for signs and seasons, and for days and years; and let them be for lights in the firmament of the heavens to give light on the earth;" then 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. God set them in the firmament of the heavens to give light on the earth, and to rule over the day, the night, and to divide the light from darkness. [Gen 1:14-19]
5th Day: Thursday - Great Sea Creatures / Fish / Birds God said, "Let the waters abound with an abundance of living creatures, and let birds fly above the earth across the face of the firmament of the heavens." So God created great sea creatures and every living thing that moves, with which the waters abounded, according to their kind, and every winged bird according to its kind. And God blessed them, saying, "Be fruitful and multiply, and fill the waters in the seas, and let the birds multiply on the earth." [Gen 1:20-23]

[Gen 1:24-25].... Then God said, "Let Us make man in Our image, according to Our likeness; let them have dominion over the fish of the sea, the birds of the air, over the cattle, all the earth and over every creeping thing that creeps on the earth." So God created man in His own image
