"Q" related conspiracies (at least some, though it ties a bunch together):

Satanic worshipers infiltrate positions of governance all over the world and maintain their power through blackmail (the more damning the better), deception (project Mockingbird, Paperclip, changing/erasing recorded history, etc), moral degradation (LGB+, Abortion, ignorance of natural/divine/constitutional rights, etc), and death (war, 9/11, 5G, FDA approved poisons in our food, etc). Mankind is purposefully perpetuated in war against itself in every way imaginable until all that remains is a self-destructive Satanic society where free will is mute. Q (and team) is working to fight and ultimately destroy said Satanic worshipers.

Flat Earth:

The mortal experience is designed by god and the world upon which it takes place is observable as a relatively flat surface rather than a spherical one. The presentation of a spherical model is done to purposefully suggest that the existence of the world on which we live is possible without a god figure (similar to how evolution is used in theory to suggest life's origins without needing a god figure).

Aliens:

Aliens, in whatever form they exist, do in fact exist and have been involved with the affairs of this planet from time to time. People have made contact with and continue to interact with aliens whose origins are outside of this planet. For selfish reasons (see "Q" related conspiracies as a possible explanation), the governments of the world have gone to great lengths to covet these interactions for themselves.

Planetary History:

Conspiring individuals (see "Q" related conspiracies as a possible explanation) throughout the ages have constantly destroyed historical records which reveal this planet's true history. Atlantis, the life of Christ, giants, ancient scriptures, apocrypha, aliens (see the "Aliens" conspiracy mentioned above), hollow earth, the Jews being the true builders of Egypt, and more have been obscured and hidden from view.

Other:

Other conspiracy theories that can't be categorized into one of the general categories mentioned above.

Q (not "Qanon" or conspiracies perpetuated by "Anons" following Q) make sense and have loads of evidence that is continually coming out... even if Q's cryptic messaging has yet to be decoded in full.

Flat earth doesn't make any sense at all to me. God can work with a spherical model every bit as well as a flat model. God has always been fair in allowing us the choice of whether or not we want to believe in Him. Otherwise, this would probably fit under "Planetary History".

Aliens actually have quite a bit of evidence to support their existence, though their exact nature (or the number of different extra-terrestrial civilizations we're interacting with) are still largely debated or unknown.

Planetary History is fairly easy to detect where information has been destroyed/obscured: just look for anything related to God and technology.

What do you folks think?
