What are some of the forms of ancient sacrifices in Europe?

In 1075 AD one ancient sacrifice was the mass destruction of Britain by the

Waka Waka Indians of the planet doomsville. They came down in their spaceships and blew up Britain. However Queen Waka Waka was killed by the Duke of York and the invaders fled back to their planet of doomsville.

Then in 1556 AD they came back and attacked again but they were stopped by the Soviet Red Army and since then they never returned.

This is why the US and many other countries have nukes. In case the Waka Waka Indians returned we can blow them up and send them back to doomsville.
