Can Creator share how the Lightworker Healing Protocol might be a more certain path to future interaction with our galactic family of diverse life forms than the development of technological space travel?

This again is an excellent question because your particular destiny does not involve interstellar travel at all in a technological sense. You were created to solve the problem of evil in the galaxy exhibited by the fallen angelics and the extraterrestrial species they have corrupted through possession and as is inflicted on most human beings as well. You are being threatened by those very alien beings because their level of corruption underlies their subjugation and manipulation of humanity to keep you dimmed down, dumbed down, and subjugated. If you are successful in healing them sufficiently so they will withdraw, making it possible for you to continue healing the entirety of humanity sufficiently, you will all ascend to a higher dimension and take up new roles throughout the universe. If you are successful and humanity is not ended by your alien extraterrestrial controllers, you will continue working on their healing from these higher dimensions, serving as a source of inspiration and providing them with divine assistance much in the same way as you obtain now from beings in the light and the angelics serving the light and protecting and bringing healing for humans in the physical. As roving ambassadors for the divine, you will interact with many such worlds and will continue to raise up the very dark extraterrestrials who have harmed humanity so greatly through the ages, because you will see from your divine perspective that they became corrupted by the fallen angels and this nearly reached the point where humanity became so corrupt they were unable to help themselves in the face of the alien intrusion that has put humanity at risk at this very moment. Time will tell if you can be successful, but you will need the Lightworker Healing Protocol to accomplish the specific and deep divine healing needed for the task at hand, to counter these evil and savage beings who have their designs on you and your world. If things work out for the better, you will continue to rescue them from their near annihilation through depravity, and risking a total disconnection from the divine—that will be the greatest of achievements by any beings anywhere, and you will be on record for all of time as the greatest of divine representatives for your achievements.
