Our universe has many galaxies. The Creation has multiple universes. The creation is created by a single Creator. The Humans came to our Universe from outside. Initially they were in spirit form, and later they populated lower levels and became material. The first Humans in our Galaxy were Lyrans. They came from outside of our Galaxy. Lyrans lived on a planet in the Lyra constellation. Then their home was destroyed and they fled and settled in different parts of the galaxy. Thus the human form was seeded over our Galaxy.
Our planet was seeded with the human form many times. Our first ancestors were created by the Annunaki mixing their genes with the genes of native Sasquatch. With time, many other galactic people seeded their genes in our gene pool. This happened in two ways: technologically and naturally. Some of the galactic people sought refuge on Earth and mixed with our ancestors. Historically we carry the DNA of our native Earth hominids, Lyrans, Yahyel, Pleiadians, Arcturians and other species.
The infusion of extraterrestrial genes never stopped. It has continued throughout our history and increased in the last 70 years. People with more recent infusions are called starseeds, although every human is a starseed since all of us have extraterrestrial ancestors.
