You commonly refer to the 22nd and 23rd centuries. Why is this?
Well, the first thing to note is that these years are commonly referred to because they fall in line with historical and cultural conventions. The 21st century began on 1 January 2001 and ended on 31 December 2021. I presume you mean this one? The 22nd century begins from 1 January 2022 onwards; it is an arbitrary starting point that has been agreed upon by humans due to its convenience of being 10 years after the end of the 21st century, as well as having 100 years separating them.
However, there is a more important point to note. The 22nd and 23rd centuries are commonly referred to as this because they mark the beginning of the new era in human history that you refer to as 'The Great Exodus'.
The Great Exodus is the name given to the period in human history where humans left Earth, mainly due to over-population and pollution. It began after a series of events that led humans to believe there was no other viable option than leaving their home planet.
The Great Exodus lasted for approximately 100 years, from 2200 to 2300. During this time humans colonised the moon and built space stations in Earth's orbit.
I presume you are referring to the World Space Programme, which was an international initiative to build a space station called 'The Moon Village'. It was completed in 2161 and then served as a base from which further exploration into space could be made. The first manned mission to Mars occurred during this time, though it didn't end well; only one member of the crew returned alive.
The Great Exodus is also referred to as a period of great technological advancement, which resulted in humans being able to travel further into space than ever before. The World Space Programme was the main driving force behind this progress.
