In their words
Positions and remarks grouped by topic, each with the exact quote and where it was said.
Angkor Wat
Coppersmith theorizes that Khmer kings first claimed pre-existing pyramids and temples, making the finest structures in Cambodia the oldest.
“So all of the coolest stuff in Cambodia is the oldest”

Coppersmith cites wood in repaired sections of the Bakong pyramid dating older than the pyramid's accepted date as a problem for the official chronology.
“The wood samples in the repaired sections of Bakong are from the 600s”

Coppersmith speculates that Angkor's vast reservoir and channel systems were built to treat or structure water rather than merely for rice farming.
“I personally think it had something to do with how they were treating the water”

Coppersmith argues that Cambodian inscriptions record dedications rather than construction, so archaeologists overreach in attributing temples to kings.
“the archaeologists make a fairly big jump between what the kings actually wrote and saying, well, this king must have built this”

Other remarks
Coppersmith observes that the Bible is unusual among ancient traditions in portraying the serpent as evil rather than as a guardian.
“So it's one of the only traditions in the ancient world where it's suggested that the serpent is evil”

Coppersmith holds that worldwide giant lore reflects memory of real events rather than myth.
“I don't believe that that's imaginary. And I don't believe it's myths. I think that it's remembering”

Coppersmith believes the oldest megalithic structures predate a flood more than 12,000 years ago.

Liangzhu culture
Coppersmith believes the carving on the King of Jade cong was scratched over an older, higher-quality relief carving.
“I do believe that it was scratched over the top of an original, very interesting, high-relief carving that you see in a lot of other artifacts”

Coppersmith argues that Liangzhu jade artifacts appear machined and too precise for the tools archaeologists credit.
“they just look machined. They look way too precise for the tools that they say built them”

Younger Dryas impact hypothesis
Coppersmith believes that if the Younger Dryas occurred as she thinks, North America would have been largely wiped clean of ancient structures.
“North America would have been just almost wiped clean”

Lidar in archaeology
Coppersmith predicts AI combined with LiDAR and other scanning could fundamentally change the debate about ancient history within about five years.
“I think you could fundamentally change this discussion in the next five years just using AI and different kinds of technology”

Great Sphinx of Giza
Coppersmith says Biondi's second Sphinx claim could be easily tested by excavating the sand pile over the site.
“you just need to move this sand out of the way and dig down and you can prove whether it's there or not”

Gommateshwara statue
Coppersmith argues that the Bahubali statue in India appears machined.

Göbekli Tepe
Coppersmith notes that the dating of Göbekli Tepe has not prompted archaeologists to redate other sites.
“don't you find it interesting that the dating of Gobekli Tepe has not opened the door to redating other sites around the world?”

Hoysala architecture
Coppersmith contends that lathe marks on Indian temple pillars constitute strong evidence of ancient machining.
“So I do think we have strong evidence for machining in ancient history”
