EoM you need to read the other threads on this very topic like these two:

the above link is a response to this next links OP but you should read the responses there as well:
Eom as far as light creation and day and night occurring in Genesis, you claim the light could have come from stars before the creation of our sun and moon. However don't forget that each verse mentions having "evening", "morning," and DAYS before the sun and moon were created. How would far away stars that surround earth on ALL sides give Earth evenings, mornings, and days before the sun and moon??
"The Hebrew word "yom" is translated as day in Genesis. Just as our word "day" can have different meanings based on its context, so can the word "yom". For example, in the Old Testament "yom" is translated to mean a 24 hour day 1109 times. It means a long, long period of time--such as an age--about nine times.
However, every time the word "yom" is used with the term evening or morning in the Bible, it means a regular 24 hour day.
Every time the word "yom" is used with a number, such as "40 yom" (40 days), it means a regular 24 hour day.
What we now see is that in Genesis chapter one God is going out of His way to emphasize that each day is a normal 24 hour day. For example in verse five He says:
"And there was evening and there was morning, one day."
Verse 8: "And there was evening and there was morning, a second day."
Verse 13: "There was evening and there was morning, a third day."
For each day of creation the pattern is the same: evening, morning, number, day. Just part of that pattern, for example using the words "evening" and "day" together, tell us it was a 24 hour day. But God tells us in three ways -- evening, morning, number -- that the word day means... an ordinary 24 hour day.
God is making it very clear: He created everything in six ordinary days."
