Genesis 1 says the sun appeared on day 4 after the fruit trees which is after 200 million years.
Genesis 1 is saying that things each only appeared on a specific day - no overlap. The only exception I think is the Garden of Eden which had plants appearing a bit later. It is generally science that suggests overlaps, not the Bible.
If one believes the truth of the creation story and is trying to reconcile it with what science thinks happened, it is good to see the Genesis account as a short and concise story that has everything in it that needs to be there for all people from all times in history to be able to understand it as needed.
In this era of history a day of creation needs to be seen as a period of time, as the Bible uses the word at times.
In this era of history it is necessary to see the creation of fruit trees as happening when plants were created and that all sorts of plants were created at that time along with fruit trees. By this I mean that the potential for all sorts of plants would have been in the first plants. The fruit trees were not created separately about 200million years ago.
So
no, Genesis 1 does
not say that things each only appeared on a specific day-no overlap.
It's a matter of probably reading it as if it is all true for a start and then thinking how it could all be true with what science says it has discovered.
And no, I don't think the Genesis 2 has plants appearing a bit later. It's all a matter of how it is read, and I'll tell you how I read Genesis 2 if you would like.
