Which Came First in Creation Heaven or Earth

The School of Shammai and the School of Hillel: the School of Shammai says the heavens were created first and afterward the earth. A parable: like a king who made himself a throne, and once he had made it he made his footstool, as it is said, 'Thus says the LORD: The heavens are My throne and the earth is My footstool' (Isaiah 66:1). And the School of Hillel says: the earth was created first and afterward the heavens. A parable: like a king who built himself a palace; once he built the lower stories he then built the upper ones, as it is said, 'on the day that the LORD God made earth and heavens' (Genesis 2:4). Rabbi Yochanan says in the name of the Sages: in creation the heavens came first, as it is said, 'In the beginning He created' and so on; but in completion the earth came first, as it is said, 'on the day that the LORD God made earth and heavens.' Rabbi Shimon bar Yochai said: I am astonished that the fathers of the world, the School of Shammai and the School of Hillel, disputed over the creation of heaven and earth. Rather, both were created only like a pot and its lid, as it is said, 'I call to them, let them stand up together' (Isaiah 48:13). Rabbi Elazar son of Rabbi Shimon said: if it is according to my father's view, why does Scripture sometimes put earth before heavens and sometimes heavens before earth? Rather, it teaches that the two of them are equal to one another.
