Ok, I will probably regret this, as a Christian for over thirty years I can offer a different viewpoint. From what I see on all sides is a lack of understanding of the Bible and how it should be understood. It is first and foremost a theological text. It is not a modern science text. God has no need for us to understand the science of creation etc to understand him, his character and his relationship with us. It is about who and why and not about how and when. The three short chapters of Genesis that talk about our beginnings are written to lay down a understanding of God in the context of the time, to correct misunderstandings (ie: one God not many gods) and create a formwork for understanding the temple. Understanding of astrophysics is completely irrelevant in this context.
We are all trained to think scientifically, don't get me wrong, I love science. The Earth is round, old and there is no firmament. Very helpful but there is also concepts that are beyond scientific observation. We tend to put up a wall called science around ourselves, if we hear something that doesn't fit inside we dismiss it or we modify the wall. Either way we often miss the point and are poorer for it. God has chosen to reveal himself through his word, not our scientific research. He will not be proven by anything else. Flat Earthers often desperately want to prove the it's flat to prove God exists (modify the wall). Many will say that the Earth is round and conclude that the Christian God therefore does not exist. Why not Both! Sorry, couldn't help myself. My point is the conclusions are both too simplistic to do the subject matter justice.
Both modern atheism and Christian "fundamentalists" both fanning the flames of the Dunning Kruger Effect. As Jesus himself said "let he who has ears to to hear, let him hear" To truly understand we must humbly listen to the what, the why, the when, the who to.
I am not here to argue or look down on others, just sharing an observation.
Flame away, it comes with the territory. I will probably ignore it. Happy to answer genuine questions, just message me.
