The Lacerta Files Interviews
Remember the Lacerta Files Interviews? Here is the English translation transcript.
Part of the interview translated to Spanish is on this page.
An audio version in English is on YouTube.
Notice the cover image is from an excellent episode of Doctor Who that tells a similar story in fiction. That is Neve McIntosh covered in special effects makeup to play Restac in the excellent Doctor Who episodes "The Hungry Earth" and "Cold Blood".
Lacerta is not an extraterrestrial alien. The interview tells the story of the first alien war between two advanced alien species 65 million years ago. Lacerta said that 14 alien species were active on Earth in 1999.
