Most of the “colonizing” happened in prehistory. It was also based out of Ukraine, don’t know if you can attribute that to the Vikings.

I think you may be misinformed.

Viking was a lifestyle or temporary occupation, not a people. The people were the Norse, and they did a massive amount of settling in the Viking Age.

This is akin to saying "most of the pillaging in history happened by people besides vikings, so you can't really attribute that to them." Yes, others colonized the areas. The Vikings also did during the Viking age.
