That is IF you don't factor that it was in God's light. Time is relative and, if as it is written, God is light, one day in God's time is as a thousand years.
Time is relative, but a period of “1 evening” and “1 morning” NEVER EQUAL TO 1000 YEARS.
You keep forgetting that there is context to the verses that indicated “day” not a thousand years in Genesis 1. 1000 years or a millennium are never mentioned or implied in Genesis 1.
And using a verse 2 Peter 3:8 is nothing more than shoddy scholarship. You don’t read one book and then use another book to find meaning for the first book, which are centuries apart.
“2 Peter 3:8” said:
8 But do not ignore this one fact, beloved, that with the Lord one day is like a thousand years, and a thousand years are like one day.
This verse shouldn’t be taken as literal. The passage used the word is "like" and "are like". The comparison of 1 day and 1 thousand years are not the same, don't have the same meaning.
Using comparison of two things along with the word “
like” doesn't mean the two words have the same meanings. The other type of word frequently used in simile is “as”.
The use of the word “like” is common used in poem and stories, especially those that used in metaphors, when comparing one thing with the likeness of another thing. This is called “simile”.
Look up “simile”, KenS.
To give some examples of similes being used, here are a couple:
“Usain Bolt runs like the wind.”
“Michael Jordan stands as tall as a mountain.”
“Athena’s eyes flash like fire.”
Is Usain really “the wind”?
No, he isn’t. It is just expression that Bolt is a fast sprinter, using simile to convey his quickness. Can human be a wind?
Is Michael a mountain?
No, Jordan isn’t a mountain. Again it is an expression using simile. Jordan and a mountain are not equivalent, and shouldn’t be taken literally.
And likewise, the goddess Athena don’t have eyes made out of fire. It is just another metaphor using the
like simile.
Do you see what I am getting at, Ken?
A thousand years are not one day, and
one day isn’t a thousand years. The Peter’s verse is merely using a simile, which the passage shouldn’t be taken literal. But you seem to be ignoring this rule regarding to simile, and use Peter's words in Genesis, as if it applied to creation of days.
This is one of the reasons why I became agnostic in 2000. I don’t trust Church interpretations and Christian interpretations of the OT, because they can twist the verses any way they like, without considering original and actual context. It is dishonest type of scholarship.
