Maybe you SHOULD look it up cause the actual owners are the ones in possession of the artifacts. No ancient Peruivians or Greeks have showed up to claim them. When the time machine brings them here, maybe then we can think about it.
Your logic makes as much sense as those who think any old bone dug up belongs to the Indians. Assumptions!
As much as i would like I cannot possibly respond to your ravings and ignorance.
Have a nice one packrat...
