Regarding how we move through space faster than the speed of light. We are allowed to explain this to you within the limitations of your ability to understand and what you are allowed to know at this time. Things are not as they seem to you. Travel is done in a different density. Where the speed of light seems the fastest to you, in 3rd Density, this is not nearly the fastest in, say, 4th Density. In 4th Density the speed of light is over 17 times as fast.
Regarding how far we have traveled. Measuring in light years or some measure that makes distance comprehensible to you would not describe the situation to you. There is a quantum leap in the speed of travel for each density leap. In addition, there are other forms of travel which we are not allowed to explain to you. Suffice it to say that if you compare the Universe as known to us, the Zetas, to your local neighborhood, then the Universe not visited by the Zetas is your Solar System. Using this comparison to show you our range, as compared to yours, you, in all the knowledge you have of the galaxies around you, have never left your house.
