While I appreciate the sentiment, I think we tend to commit the sin of ethnocentrism when we assume that the people of old were so crass and ignorant. I am not convinced by the fundamentalists nor the anti-religious atheists who insist that we read Genesis literally. Within the Christian tradition, from the time of the Church Fathers, Genesis chapter one has commonly been interpreted metaphorically (see below). Margaret Barker asserts that Genesis chapter one is a narrative about the construction of Solomon's Temple, which served as a sacramental microcosm of creation.
I also want to point out that the biblical literature has not really been edited by "kings, popes and monks." We have manuscripts that date pretty far back to late antiquity. The biblical texts we possess are generally considered to be pretty decent in their accuracy.

Clement of Alexandria
"And how could creation take place in time, seeing time was born along with things which exist? . . . That, then, we may be taught that the world was originated and not suppose that God made it in time, prophecy adds: ‘This is the book of the generation, also of the things in them, when they were created in the day that God made heaven and earth’ [Gen. 2:4]. For the expression ‘when they were created’ intimates an indefinite and dateless production. But the expression ‘in the day that God made them,’ that is, in and by which God made ‘all things,’ and ‘without which not even one thing was made,’ points out the activity exerted by the Son" (Miscellanies 6:16 [A.D. 208]).
Origen
"For who that has understanding will suppose that the first and second and third day existed without a sun and moon and stars and that the first day was, as it were, also without a sky? . . . I do not suppose that anyone doubts that these things figuratively indicate certain mysteries, the history having taken place in appearance and not literally" (The Fundamental Doctrines 4:1:16 [A.D. 225]).
St. Augustine
"It not infrequently happens that something about the earth, about the sky, about other elements of this world, about the motion and rotation or even the magnitude and distances of the stars, about definite eclipses of the sun and moon, about the passage of years and seasons, about the nature of animals, of fruits, of stones, and of other such things, may be known with the greatest certainty by reasoning or by experience, even by one who is not a Christian. It is too disgraceful and ruinous, though, and greatly to be avoided, that he [the non-Christian] should hear a Christian speaking so idiotically on these matters, and as if in accord with Christian writings, that he might say that he could scarcely keep from laughing when he saw how totally in error they are. In view of this and in keeping it in mind constantly while dealing with the book of Genesis, I have, insofar as I was able, explained in detail and set forth for consideration the meanings of obscure passages, taking care not to affirm rashly some one meaning to the prejudice of another and perhaps better explanation" (The Literal Interpretation of Genesis 1:19–20 [A.D. 408]).
