Was the New Age movement created as an Extraterrestrial Alliance disinformation campaign designed to disempower humans by turning them away from true spirituality?

This is quite true. This is its origin and its purpose—to seduce the humans with spiritual impulses into thinking they can create their own brand of faith, and work on their own independently, or with some compatriots doing the same, and make something useful happen. This is true to a quite limited extent, but will not be sufficient for them to achieve true enlightenment, nor to save humanity or the planet from calamity. It is a very effective means through which the Extraterrestrial Alliance, in collaboration with the dark spirits, have misdirected humans, causing them to drift away from their religious roots and abandon the idea of a God who can be prayed to and summoned to help. The consequences of this choice continue to play out in human culture, which is worsening in many ways from this lack of divine awareness and outreach to establish better connections, and rebuild the bridges for communicating with the divine realm, and appreciating the importance we represent as the true answer for the threats to humanity, which are mounting. It is not that all such efforts are faulty and meaningless, it is only that they are so limited in their power. This is because humans are limited in their power as a consequence of their physical state of being. This was not their original capability when first created but has been imposed on them as severe limitation through manipulation of the genome by the extraterrestrials, to disconnect people from the higher realms to a significant degree, and also to disconnect themselves from the deep subconscious which is the intuitive gateway to higher awareness, and as a consequence resulting in many, many emotional disturbances and inner conflicts that cannot be resolved and healed.
