The Huge Difference between an
Old Earth timescale and a Young Earth Timescale

Old Earth
If the Earth is 4.5 billion years old, then if all of history were figuratively represented in a
24-hour day:

The Big Bang would have occured at:
00:00.00.000

And the appearance of mankind would have occured at:
23:59.59.875
[23 hours, 59 minutes, 59.875 seconds]

Young Earth
If the Earth is 6,000 years old, then:

God created at:
00:00.00.00

And mankind was made at:
00:00.00.23
[zero hours, zero minutes, and 0.23 seconds]

The huge difference between Old and Young earth timescales can be seen here.

If the earth is 4.5 billion years old, then mankind has only appeared very recently, so men and women would not have come into existence in the beginning, but rather towards the end!

If the earth is 6,000 years old, and mankind was made on the 6th day by God, then men and women came into existence in the beginning!

Matthew 19:4
"Have ye not read, that He which made them at the beginning made them male and female" KJV
""Haven't you read, He replied, that at the beginning the Creator made them male and female?" NIV

Here we see that Jesus says that the Creator made man and woman "In the beginning".
Which of the above timescales fits that statement by Jesus?

The Old earth model with mankind not appearing in the beginning, but only very recently?
or
The Young earth model, with mankind being made during God's creative week?
