This is exactly the same as 2000 BC. In an attempt to be neutral with regard to religion, some people prefer to refer to years 'before Christ' as 'Before the Common Era' rather than 'Before Christ'. You will sometimes see something like 1776 CE, which would mean 1776, Common Era, exactly the same as 1776 AD.
Assuming that BCE is a renaming of BC and CE is a renaming of AD of the calendar devised by Dionysius Exiguus in 247 Anno Diocletiani which he designated 531 AD since he calculated that Jesus was born 531 years earlier, becoming his year 1 AD, which was preceded by 1 BC as zero was not invented for another 500 years or so, then between 200 BCE and 2000CE there are the 199 years 199 BCE to 1 BCE and the 1999 years from 1 CE to 1999 CE, making a total of 199 + 1999 = 2198 years between 200 BCE and 2000 CE (exclusive). However, as people were celebrating 2000 CE as the start of the third millennium CE, the second must have run from 1000 CE to 1999 CE and thus the first must have run from 0 CE to 999 CE which means that in the BCE/CE calendar there is a year 0, which means between 200 BCE and 2000 CE there is an extra year, meaning there are 2199 years between 200 BCE and 2000 CE (exclusive). Which dates have been corrected for this extra year in the BCE/CE calendar over the BC/AD calendar I would love to know; for example, Julius Caesar was assassinated on 15 March 44 BC, so is that 15 March 43 BCE?
The area of the Sahara had already long been a desert by 2000 BCE. Lack of precipitation and a rise in temperature had dried up the area by 3400 BCE.
It is believed that daoism started over 2000 years ago
Astronomically, it would be 2000 to year 0 and then 1 equals 2001 years. The Roman calendar we use today had an omission in it - not counting the year zero but rather, starting with the first year. It went from 1 BC to 1 AD missing a full year. By this measure there would be 2000 years only.
540 BCE. In years BCE (BC), the years count backward until the year 1 BCE is reached. The year 1 CE (AD) immediately follows 1 BCE, and begins counting upward; there is no year 0.
2000 BCE or less
If the year is 2000, then 3000 years ago would be the year 1000 BCE (Before Common Era). This is calculated by subtracting 3000 from 2000, resulting in -1000, which corresponds to 1000 BCE in the Gregorian calendar.
The year 992 BCE

The year 10500 BCE ended at the beginning of the year 10499 BCE.
2000 BCE. This means 2000 years before common era. it used to be referred to as "bc" until the scientific community decided that that was too centered on Christianity so they changed it from "bc=before christ" to "bce=before common era" and "ad=anno domini (the year of our lord)" to "ce=common era"
The year 10500 BCE ended at the beginning of the year 10499 BCE.

No one knows for certain, but it's estimated to be around the year 2000 BCE.
