There are 40 billion Earth-sized planets orbiting in the habitable zones of sun-like stars. From many of those we came. Millions of us have been labeled as "Star People" aka. Indigo, or Hybrids, physically speaking. But the whole reality stretches far beyond what most humans can understand or accept.
On the other hand, there is a direct alien interference that kidnaps humans, mixes their sperm or ovules with alien, and then populates new planets with a mixed race, exactly as what happened on Earth millions of years ago. There is also a direct alien interference that kidnaps female humans, impregnates them with a mixed race of human appearance, and makes them give birth to babies that look human but are actually hybrids. And yet, the most important interference manifesting on Earth is spiritual.
