But the Genesis 1:5, 1:8, 1:13, 1:19, 1:23 & 1:31 make it quite clear that each creative day, comprised of the evening-and-morning, not to a period of 1000 years.
There are no between line in "And there was evening and there was morning, the first day.", or for the 2nd, 3rd, 4th, 5th or 6th day.
Mixing 2 Peter 3:8 verse with Genesis 1, is not reading between the lines: it is complete reinterpretation by wishful-thinking Christians.
Beside that, 2 Peter 3:8, is nothing more than similes, using words such "like" or "as" depending on translations, are symbolic meaning, not literal meaning:
Using
"is like" and
"are like" clearly should be read as symbolic, not as literal. It (2 Peter 3:8) doesn't say:
...one day is a thousand years...
...or...
...a thousand years are one day.
That's the only way 2 Peter 3:8 can be read as literal, by dropping the word "like" from the verse.
And your
"is like unto" is not to be taken as literal.
This can't be any more clearer.
