Source has defined the boundaries for itself. Source needs to experience itself as an extended form. So, each race holds its own consciousness and holds it within their own sphere of influence. These are like a combined set of rings, all are frequency.
Source exists in a void and is using the universe which also sits in nothingness applies relationship and experience to physicality so it can define itself via reflection.
And so even spirit realm is defined and confined to a specific frequency.
The UAP disclosure is about humans not being that important as a civilization, as they are part of many races.
If you were part of a different race and a human mentioned a human concept to you, no being there would know what was being talked about, and so even disclosure is defined by humanities understanding of disclosure.
