In a debate or conversation, both parties state beliefs and, if it is a debate, which this appears to be, both parties state sources and/or studies conducted by themselves or others.

It will be hard to prove anything about skin colour of an ancient civilization, especially when the civilization just did not give a fuck about skin colour.

I think they had mixed skin tones (as in a bit of both) if there were white people in Greece. People can and always have been able to move to a different country, and thus, the country will have a bit of a mix.

Ricecake has given plenty of sources. You should also drop a few sources if you want any chance of recovering from this absolute ratio. Please grow up, educate yourself, all civilizations have had multiple skin colours, most just don't give a fuck, and learn how to have a debate and find sources.

Edit:

When starting a debate, you should also have sources to back yourself up, otherwise it's an accusation, not an argument or debate. Please come back when you have sources and learn how to debate.

I hope everyone involved has a day as good as they are.
