Please stop using "Christians" to mean creationists, as there are likely upwards of a billion Christians who do not interpret the Genesis story literally.
Amen brother, and that's where I have a gigantic issue with society today painting all christians out as fundamentalist bible thumpers.
Again I will reference my catholic education class. Last night we discussed the catholic church's views on creation. In the catholic tradition genesis (and possible other parts of the Torah like exodus but we didn't get that far) is interpreted as allegory. In other words it is non literal and meant to convey a spiritual truth not a factual one.
Here's how they broke it down. The first chapter of genesis is actually a Semitic oral traditional creation account. It's not christian or Jewish, semetics are actually a whole region of peoples not exclusively jews, although they've become almost interchangeable today. So that's part of why genesis is so similar to other origin mythologies of the region like gilgamesh which is Persian.
The format of it is like a poem. God did something, and said it was good, a day passed. God did something, said it was good, a day passed. You can clearly see the oral tradition being passed on here and that seems to be what the author is conveying, that this is a simple story of creation not a factual account. It is not meant that it took literally 7 earth days to make everything.
The main takeaways from it then are spiritual truths that god made stuff happen, whether you call it evolution or intelligent design or whatever, god had a hand in it. Back then most civilizations worshiped many gods and many of them were stars and the sun and stuff so this monotheistic idea that there was one god and that god created the stars and sun was a big idea and a big deal. In essence the one god is above all the others, he made the other god's almost. And the later come birds and fish, plenty of cultures worshiped versions of those two. Again, they came from the one god.
And then when man finally showed up he was created special. Whether we evolved from other stuff or whatever, the point is man has something animals don't.
There's also a second creation account at the start of chapter 2 where is says god formed man from clay and breathed life into him. This basically confirms that these are oral traditions being jotted down cus there's two of them. The author took two stories he liked and recorded both. The second one is important from a spiritual context because it examines god's close relationship with man, that man is divinely inspired.
Nothing in either of those myths contradicts evolution. Indeed that missing link scientists are always looking for might just be whatever happened when the story says god breathed life into man. At some point our brains starting thinking, rationalizing, and
knowing stuff, beyond what the smartest creatures are capable of. We become self aware. Science may eventually uncover that link and we'll be like holy crap how was *that* possible?!? I don't think the creation myth is that far off when view in that context.
