Gen 1 talks about the creation of the entire universe, not just the earth. The first earth, which was merely a three-dimensional 'blob' of 'waters', is the contituent of all matter. a part of which was used to form the planet Earth (the 'waters below the firmament'), once GOD instituted 'gravity' into the universe. The 'waters above the firmament' is the boundary of the universe, and the firmament of heaven is the void of space. We are not made of 'star' material, because we came from the earth, which was formed (day 3) before the stars were formed (day 4).
GOD did create the angels, but they were Adam and Eve. No where else in the creation account is there any mention of 'angel' creation, so Adam and Eve have to be them. To believe otherwise, is to add to the Word of GOD, which is a 'taboo'. GOD did not leave us ignorant of HIS Arch enemy, Satan, we just refuse to believe His Account as being perfect (GEN 1), and instead, beleive the myths and fable tha men have created surrounding the angels. Adam became the devil when he chose to decieve Eve. Read what she said GOD spoke as the Commandment, as compare to what HE told Adam, and it is clear she was already deceived.
