So I think it is safe to say that for one thing we know that ET's are here and have been here even before our conception.
We know that they are both directly & indirectly involved in humankind, undertaking whatever it is they need or want to do, despite whether we believe it to be ethical/non-ethical.
We can also safely assume, that what they are doing is beyond ANY of our own understanding.
So what can we do?
We can try to understand & process it as much as we are able, and then simply continue to experience living as a human being on Planet Earth. The ebb & flow of life will continue on...What else can we do?
The Universe doesn't give us anything we cannot handle. Even under the murkiness and the mess of what we have created on this planet, despite our battle wounds & life scars, Humans are resilient, strong and innately beautiful. We can redeem ourselves...
Thanks to the ET experience & presence on Planet Earth, it is THEM that give us the gentle 'nudge' we need to expand our boundaries beyond the comfort of our own fringes...
