As political unit, Ukraine started in 9th century as Kingdom of Rus. Moskovia as a political unit started in 1157 as the Principality of Vladimir-Suzdal. Saying that Russia started in Kyiv is like saying that Argentina started as the Kingdom of Castile in the 9th century or that the USA started as the Kingdom of Wessex in 6th century. There is a connection, but a VERY remote one.
