Woody thinks that it was the same people that left Africa all those years ago, that arrived by dingy in UK.
He thinks that thousands of years ago, people like Lucy, one day decided to set sail, from Africa, for UK because she heard on the grape vine that the benefits were better.
Assuming a 25 year generation gap, and assuming that children move away from home, perhaps some a few miles, others a couple of hundred miles, occasionally some thousands of miles, it doesn't take many generations for "an ethnicity" to leave Africa and arrive in UK, interbreeding with Neanderthals and other ethnicities on the way.
But they weren't heading to UK, they were just exploring and some of them chanced on UK, eventually. They populated Asia, Middle East and Australia first.
It was much later that they spread to Europe.
Migration is a natural part of human development and evolution. White explorers weren't the only ones who knew how to build boats. They weren't the only ones to rape and pillage other lands. But their capacity to fool themselves into believing that they're superior to other ethnicities knows no bounds, and it shows time and time again in these threads.
