Genesis chapter one covers a time span of between 12 & 14 billion years. Genesis chapter two begins 6,000 years ago. Darby and dispensationalism are
YEC (Young Earth Creationists) so from that perspective one day is equal to 1,000 years. That would mean Genesis chapter one begins 12,985 years ago. There is a nano diamond comet that hit the earth at that time so we can use that as a
marker. There are people like Gerald Schroeder that teach a day age theory where the Bible begins 12.985 billion years ago. According to Schroeder each day is half the length of the day before it. Or perhaps they follow the Fibonacci numbers 1 2 3 5 8 13 21. Or 21 13 8 5 3 2 1. So there are different interpretation and understandings of Genesis. None of them need to be mutually exclusive. They could all be true at the same time.

It says 'days' in the bible I read, it seems your mate Ussher agrees. When you need to make things up like '12 & 14 million years' and 'One day is equal to a 1000 years' in order to try and force Genesis 1 to fit reality it should set alarm bells ringing.
What do you think of this:
2 Peter 3:8–9 reads:
‘But do not forget this one thing, dear friends: With the Lord a day is like a thousand years, and a thousand years are like a day. The Lord is not slow in keeping his promise, as some understand slowness. He is patient with you, not wanting anyone to perish, but everyone to come to repentance.’
The first thing to note that the context has
nothing to do with the days of creation. Also, it is not defining a day because it doesn’t say ‘a day
is a thousand years’. The correct understanding is derived from the context—the Apostle Peter’s readers should not lose heart because God seems slow at fulfilling His promises because He is patient, and also because He is not bound by time as we are.
The text says ‘one day is
like [or
as] a thousand years’—the word ‘like’ (or ‘as’) shows that it is a figure of speech, called a
simile, to teach that God is outside of time (because He is the Creator of time itself). In fact, the figure of speech is so effective in its intended aim precisely because the day is
literal and contrasts so vividly with 1000 years—to the eternal Creator of time, a short period of time and a long period of time may as well be the same.
The fact that the passage is actually contrasting a short and long period can be shown by the fact that Peter is quoting
Psalm 90:4 (Peter’s statement ‘do not forget’ implies that his readers were expected to recall something, and this passage has this very teaching). This reads:
‘For a thousand years in your sight are like a day that has just gone by,
or like a watch in the night.’
This is
synonymous parallelism, where a long period of a thousand years is contrasted with two short periods: a day, and a night watch. But those who try to use this verse to teach that the days of Genesis might be 1000 years long forget the additional part in
bold. For if they were consistent, they would have to say that a watch in the night here
also means 1000 years. It’s difficult to imagine that a Psalmist (
Psalm 63:6) is thinking on his bed for thousands of years or that his eyes stay open for thousands of years (
Psalm 119:148).
