When creating a timeline, you would typically want to arrange the events or periods chronologically. Based on the terms you've provided, here’s how you should order them:
- More than 2000 years ago (this refers to any time prior to 2000 years ago)
- Before 2000 years ago (this is similar and may overlap with the previous phrase)
- 2000 BP (BP stands for "Before Present," which typically refers to the year 1950, making this about 2000 years ago)
- About 2000 years ago (this refers to the time around 2000 years ago, around the start of the Common Era)
- Before 2000 (this is a less common phrase, but it refers to the time leading up to 2000, which could be inclusive of the previous periods mentioned)
So the order would reflect the progression from the furthest past to the more recent past. The key point is to be consistent with the terms you choose and ensure they are understood by your audience.
