The abduction programme to create hybrids has been going on for a long time. Abductions appear to be linked to family lines, likely related to a gene/blood/trait that interests them.

Insectilins lead the greys, along with the Reptilians.

The hybrids are already living among us.

If you wish to know the details, I recommend you read/listen to Dr David Jacobs' "Walking Among Us."
