Yes, we are close to Russians (we share Slavic DNA), but now we are closer to Poles. According to scientific research, Russians also have some Mongolian DNA.
And by the way, I have some Czech DNA
The Muscovite principality arose much later than Kievan Rus, and there is a legend that Russians arose from Ukrainians.
And in general, do you know the history of Ukraine well? It is better to remain silent and deal with the situation normally, if you have time.
I don't want to argue so as not to spoil our mood.๐
