Dude, half of your post references a site specifically created to prove something that is considered fiction in the world of science. You are in no position to be criticizing Wikipedia.
Wikipedia has far better, much more scientific sources, that article included.
The issue here is that we have no idea where most these stones came from, we can't date them, we can't even confirm their origin.
These things are CRITICAL in archeology. Archeology requires context in order to be beneficial scientifically. Without that context, these are just stones that science can't take seriously.
And it doesn't, because these stones have no context, and there is nothing else in South American archeology that DOES have context that at all supports these stones.
Keeo in mind, these stones aren't just being used by creationists, they are also being used by ancient astronaut theorists. That's not particularly good company.
