For the time being, human civilization employs the Gregorian chronology which starts with the legendary birth year of Jesus Christ and takes this year as the boundary. The time before is called BC, and the time after, AD.
For Bit Era System, 2009, the year Bitcoin was born, will be set as the boundary.
To me, this is honestly a bit ridiculous if you go back as far as 2000+ years and go so far as to imply that the period before and after 2009 should be called
"before Bitcoin" BB - or
"after Bitcoin" AB - like comparing Christianity to Bitcoin, by which you only add fuel to the fire of those who say that Bitcoin is a religion.
This is the biggest change that Satoshi Nakamoto's creation of Bitcoin has brought to human civilization. Satoshi Nakamoto is the Creator of Bit Civilization who pioneered and created the world. He dug out the first block of Bitcoin, which marked the genesis of Bit Civilization. That is why he chose that name.
What do you think?
I think (and I hate to repeat myself) that you have gone too far in a direction that makes very little or no sense at all. It’s hard for me to imagine someone fantasizing about some kind of Bit civilization and wondering why the first block was called Genesis (as if that wasn’t self-explanatory).
Maybe it would be good to start writing some fantasy novels, you have a sense of the subject, and it sells really well.
