You can find this image in Satanism and also in other places like corporate logos and even in the Military. The red/black colors are often seen in heavy metal music and movies.

The red and black colors are the 2 slowest vibes in colors and low vibes generate low vibes for the viewer but this doesn't mean the colors themselves are bad. Satanists just use it for this reason. Also, believe it or not, the Satanists have a Satan flag which is a red circle with a black core on a white background. The Communist Russia flag was also almost all red.

The circle with upside down star is what the home-planet of an ETI looks like from a telescope. The ETI are worshiped from an area near Tibet. This very evil cult was the primary cult in the ancient times. They simply converted humans into their religion but also ran disgusting rituals. The show "True Detective" is about this cult. It shows how the cult is mixed up with the Gov, Military and even Corporations. The competition of this cult is mostly the Rothschilds who run the Baal money cult where they manipulate humans to worship money.
