Pronunciation evolution differentiated U and V more and people started differentiating that with an extra sign. As in, the Roman V was pronounced kinda like both and not like today’s V - the Roman symbol V is not the modern letter V. You may notice that modern media about ancient Rome have been making Vs sound more like Us.

Major missed opportunity not making Canaanite and Greek head be turned a different angle

Chinese movies, historical and fantastic, have a raging hard on for rows and rows of faceless mooks pushing against each other. Only the leader is allowed to have individual fights. You want the historical approach, you look at China. It’s the whole Confucianism root.

We didn’t just start using our brains like that in recent time only. There may have been a few Albert Einsteins in the stone age but if they couldn’t spread their ideas, then that civilization did not have that knowledge. Leather tanning and meat conservation can be discovered easily, but it has to be rediscovered every time there’s a new group of 20 people, it doesn’t get transfered to be improved upon over the centuries.

The problem your reasoning is missing is scale. We know you can’t build the Great Pyramid if your busiest cultural center is a village of 200 people in the closest 100 km and they couldn’t communicate.

And all our tech is based on improving upon something that exists. No one can conjure a microchip and a cell phone out of thin air.

Brendan the navigator, 6th c., but the story about “Saint Brendan’s island” is not proven to be about America AFAIK. Or true. It’s a legend about a blessed island that may be a religious myth.

There’s a ton of legends of sailors finding a vanishing island, an island of plenty, the island of apples, that various theories have attached to the Canaries or Azores and such IINM. Saint Brendan is just one among those, so it’s hard to assume it’s fact.

Also, Leif Erikson was in year 1000. And there is a strong suspicion that diseases did play a big role and made it a shitshow.

So you mean the oldest pyramid, not the last? The pyramids in Egypt were built starting around ~2660 BCE up until ~1530 BCE, with the 3 in Giza through 2600 to 2530 BCE, roughly. All dates give or take maybe 10 years. The dates you have would likely be a range for the first of the 3 pyramids in Giza.

? The last pyramid in Egypt (other cultures like the Nubians built their own) was built by Ahmose I in the mid to late 16th c. BCE, IINM. Not sure what you’re thinking of for 2611 BCE, even the Giza pyramids are within the hundred years after that.
