The Zeta's recently offered the opportunity for questions to be invited from people outside of the circle that we sit with regularly. These are their responses to the questions asked:
Z: Zeta Communicator
S: Sitter
 1. Why were/are alien implants used?  
Z: Implants used on humans - they are used for tracking purposes – this is already known by humans.
S: Were they all used for tracking?
Z: Initially yes, but as they have progressed, the etheric implants are used for a variety of functions; as the understanding of the human physiology and consciousness has progressed, different types of technology have been implemented that are less invasive.
S: Are you talking about the implant technology from the Zeta race only, or other races too?
Z: We only speak for ourselves. So the first older technologies were implemented in your 1940s time frame, the newer technologies around 25 – 30 of years ago of your timeframe. And of course, now there are other technologies based in light and frequency.
S: Is there ever the need for a physical implant in a human these days, or have all physical implants been replaced by the newer technologies?
Z: Physical implants are too invasive. The potential for the body to reject them is high.

2. Have these implants been implanted in people who have certain traits? If so, what are they?  
Z: They are hybrids – it is nothing to do with human peculiarities.
 
3. Is it possible to remove these implants with psychic surgery for the benefit of the human being?  
Z: No
 
4. Is there a race or being that can help and can be asked to do this?  
Z: No you can not summon a being – the human ego is too powerful. You would interfere with the removal process. Also, the human container would need to be acclimated to the heterodyned form of the race. These are things that humans believe about themselves to be true.
S: When you’ve been asked to removed unwanted attachments and implants, by humans, that have been put there by unknown races, you have done that.
Z: Yes
S: And you’ve done that with the understanding of what you were doing...
Z: That is correct, yes.
