Thank You for creating such a well written and thought out article!
I would tend to agree that what we refer to as "aliens" were advanced extraterrestrial beings who may very well have had their hand in jump starting the human race aeons ago.
Mainstream is now going public with all sorts of accounts on advanced races that could have had a role in genetically modifying us. What was once confined to "alternative history" --- new discoveries and translations of Sumerian, ancient Egyptian and Mesoamerican tablets and sacred texts --- shed light on what was previously regarded as science fiction. Now science fact.
This world is currently experiencing a shift in consciousness as more people wake up to the fact that not everything is as it seems. As these numbers grow, the "powers that be" ... make that, "powers that were", will have less control on the truth destined to enlighten the masses.
Peace!!!
The ancient texts have lots of interesting content that can show some involvement of such extra terrestrial civilisation in our history. I used to watch a lot of Ancient Aliens on the History channel and though I think that some of the ideas they stated were too out there, some other ideas are surely worth considering.
