How do I manually update a old Mac?

crwdns2934249:0crwdne2934249:0:

I have received an old Mac Pro G5 running Mac OS X Leopard, and have tried updating it to its newest possible form. When I downloaded Mac OS X High Sierra and even Snow Leopard, it says “Can not update” when I try to open the update file (Through USB).

By the way, I was connected to the internet by ethernet.
