How about submitting these things to medical testing? MRI, anyone?
These corpses date back more than a thousand years and were entombed in diatomaceous earth. Hence, they have been completely desiccated and an MRI would be unrevealing. X-rays do show that one specimen has eggs. Nevertheless, they have their own surgical implants, jewelry, and an intact consistent skeletal structure that belies the debunker cult claims of being fabricated from spare parts.
Everyone says to show them the bodies. But when bodies are shown, the goalpost is moved again.
Fortunately, the discoverer has kept them out of the hands of both the Peruvian government as well as CIA/Naval Intelligence. Otherwise, this evidence would go the way of the crash debris.
