Figurative. Genesis 1 is a song of praise to the miracle of creation – not a science paper. The average ten year old can see that it’s not meant to be scientifically accurate. Only funDs and fringe cults (and ironically some atheists) can’t see the poetic elements that are obvious to everyone else. Especially the repetition of phrases and the structure/rhythm. Numbers also had great symbolic meaning for the Jews, especially the number 7 which was considered "divine" and "perfect."
As far back as Philo, 1st C, followers were warned NOT to read it at face value, and that the "days" referred to are not 24 hour "days."
The Hebrew word for "day" (yom) ALSO means 'period of time' and this is how it is used in Genesis 1.
Hebrew had only 8700 vocabulary words and many words had multiple meanings.
The idiomatic expression "evening and morning" signified the ending of one period and the beginning of another.
Psalms 90:4 "For a thousand years are but a day in your sight."
2 Peter 3:8 "For a thousand years in your sight are like a day."
Showing time is meaningless to God. (There was no word for and no concept of a "billion.")
In 408 AD, Augustine warned the faithful not to read Genesis 1 at face value, or to be overheard spouting absurd ideas about the physical world by non-believers. Such ignorance just brings ridicule to all people of faith. (See "On the Literal Interpretation of Genesis").
Thomas Aquinas echoed the same ideas in the 11th C, as did the well respected Rabbi - Maimonides - who made a warning very similar to that of Augustine.
Even when reading a text 'literally', one is still obliged to research the symbolism, metaphorical expressions, idioms, and at the very least, the correct translation of the terms, and of course, to understand the cultural context.
Jews even Orthodox Jews, as well as all mainstream, educated Christians know that the fundamentalist/literalist reading of Genesis 1 - 11 is LAZY and sows confusion where none needs to be.
They read without exegesis, without scholarship, and consequently make all people of faith look ignorant.
Remember also, that they had no system of writing until appx. 1000 BCE, and poems/songs have historically been a common way for people to remember things. (Think back to your kindergarten days). Not to mention that Genesis 1 - 11 were added much later, after Moses, to give the Hebrew tribe a sense of origins. There were no Hebrew people at all until Genesis 12 when God spoke to Abraham. That is a fact.

"We the undersigned, Christian clergy from many different traditions, believe that the timeless truths of the Bible and the discoveries of modern science may comfortably coexist. We believe that the theory of evolution is a foundational scientific truth, one that has stood up to rigorous scrutiny and upon which much of human knowledge and achievement rests. To reject this truth or to treat it as “one theory among others” is to deliberately embrace scientific ignorance and transmit such ignorance to our children. We believe that among God’s good gifts are human minds capable of critical thought and that the failure to fully employ this gift is a rejection of the will of our Creator. To argue that God’s loving plan of salvation for humanity precludes the full employment of the God-given faculty of reason is to attempt to limit God, an act of hubris...We ask that science remain science and that religion remain religion, two very different, but complementary, forms of truth."
