Lol, the joke is just that this is the inverse of how this meme usually works, since counting backwards in BC is forward in time.
My man I think he was making a joke by pretending that the inversion is so obvious he was trying to understand the joke
Oh... I see. I was trying to figure out the humor.. I wasn't getting the reference to the other memes at first lol.
I get that, but I don't get the joke. Is the joke that after bows were invented, people started using them?
The joke is that the format of this is normally
So when you first see it you're like "haha, but wait that's a bow..." then you remember "ah yes, it's BC"
Oh ok, so it's a play on an existing meme format. I'm not a memexpert so didn't understand the joke.
I've also never seen an original of the format this is from, glad I wasn't the only one confused
It's a meta meme, playing off of the format that usually has people doing something silly before the time something was invented. But it's backwards because it's BC.
Examples:
I think the joke is that people who don’t know how years work would think 4999 BC was before 5000.
The Final Countdown! Ba da da dah! Ba da da da dah! Ba da da dah! Ba da da da dah da dahhhh! It's not a trick Micheal, it's an illusion. Tricks are what whores do for money.
I keep coming back to this meme and it's so bad but that makes it so perfect. This is honestly beautiful artwork
People on ships before the bow was invented:

The reason this meme doesn't work is because people in 5001 BC also had bows.
It would have a better punch if you took something like the burning of Alexandria in 48 B.C. or the stabbing of Julius Caesar in 44 B.C.
