I don't like to pretend I know exact details of anything but I do resonate feelings similar to a lot of what you posted. I've always known that humans were not originally native to this earth, and I've always known deep inside of me the feeling of our ancestors, I can remember them, see them when I close my eyes. They are not just our creators but we in a sense ARE them, and are evolving more and more into what they were every day. Or who knows, maybe we are evolving into something new and better.
I had a very vivid vision a few years back that "they" showed up here and it changed everything, it was scary and good but it did freak me out because I later read about that freaky project blue beam internet report thing and it matched the dream I had almost perfectly.
All I know is something is coming and as long as we reside within a place of open minded love and light all will happen as it's supposed to and we will be fine.
