If I understand correctly, there is yet again a large group of small grey aliens that have come to Earth. Why did they choose this planet to colonize?
This race of aliens are known as the scavengers who take over what other civilizations built when they colonize planets belonging to other races. Think of them as the garbage collectors of the universe. They take out the "trash" of other races that have degenerated to a low frequency.
Unfortunately, that applies at this point to the humans on Earth. But the scavengers have not taken into consideration that the Original Ones are here too; diamonds lying in between what they regard as human "trash". It is because of your presence here that the Infinite One has put this planet under quarantine — no aliens may colonize it or invade it in any way. By living your Godhood in humble majesty and wholesomeness, you are preventing the destruction of humanity.
