I never claimed that "1 haplogroup made the Greeks", whatever that means. I'm arguing that ancient Greeks carried various lineages and we know which because archeologists have found their remains and geneticists have sequenced them.
What I'm trying to explain to your thick small little Rum brain is that for a subclade to belong to X ethnic group, one of the requirements is that it should match the time period of that ethnic group's existence.
Ancient Greeks did not exist 16,000 years ago, so a subclade that is that old cannot be in it's entirety, an Ancient Greek subclade. But younger subclades of that branch, can be Ancient Greek because they match the time period when Ancient Greeks lived and it's also supported by ancient DNA of sequenced Greeks.
I gave you three examples, which you ignored, conveniently. Anyway, I'll send them again:

^ These are 3 examples of ancient Greek subclades which fit the time period (1717BC;1818BC;1085BC TMRCA of those subclades in that order) and are also found in ancient Greek samples. BUT they are not found in modern Greeks at all. Do you want me to give you more examples? There's plenty more.
