Except that the same account in Genesis 1 clearly state he made the Sun, Moon and Stars on day 4. The Biblical account directly contradicts the Big Bang and evolutionary sequencing, thus one or the other is in grave error.
Doesn't say that. It says God made "the two great lights...the greater one to rule the day and the lesser one to rule the night."
From the beginning of Christianity, theologians knew there was something funny about the days of Gen 1, because how can you have morning and evening on days 1-3 if the sun and moon aren't made yet? They saw right away there was something odd going on.
My personal opinion is that the sun (at least) was created with the light on day 1. Earth then had a hazy, perpetually cloudy atmosphere like Venus's. There was day and night but no heavenly bodies were visible. The creation of the plants on Day 3 released massive quantities of free oxygen into the air, and our atmosphere went from (if I remember my biology classes right) a cloudy reducing one to a clear oxygenating one. On Day 4, the sun and moon and stars first became visible to the surface of the earth and could be used to tell time.
Perhaps Genesis chose to say "the two lights" rather than "the sun and moon" for a reason. Because it wasn't the bodies themselves that were made on that day, just the light from them.
You are making the "grave error" of not differentiating between "creating (from nothing) and "forming" (or "shaping") materials that already had been created or formed...
Stars, Earth, etc. were not "created". They were "formed" by God -- just as the physical body of Adam was formed by God from "the dust of the ground" (light elements that God had created ex nihilo plus heavier elements that He caused to be formed by fusion in the cores of stars and supernovae.)
The "grave error" or "conflict" exists only in your mind -- because, you, apparently, neither understand Genesis nor the scientific description of Creation, aka "the Big Bang".
Conflict between Genesis and science exists only in the minds of folks who are ignorant of one or both -- or who make their livelihood by deliberately (and falsely) teaching that such a conflict exists.
