Barbara Marciniak’s channeling of the Pleiadians described in her book, Bringers of the Dawn, says that they are of a Reptilian lineage, and that we are, too. Is that true? Are the Reptilians among the four root races of human you have described?

It is true the Pleiadians are of the Reptilian lineage. It is also true that humans have some elements of DNA from that race, but you were not created by them per se. You have been modified significantly by them through the millennia because of their tinkering with your DNA. That is a significant distinction and is not the same as their creating you to begin with.
