Which informal logical fallacy is committed in the following argument: "No one has shown that aliens did not create the crop circles. So the crop circles must have been made by the aliens"?

Correct option is B

· The Appeal to Ignorance (argumentum ad ignorantiam) fallacy occurs when a claim is considered true simply because it has not been proven false, or vice versa.
· In this case, the argument assumes that since no one has disproven that aliens made the crop circles, it must be true that aliens made them. This is logically flawed because the absence of disproof is not proof of a claim.
· A proper argument would require evidence, not just the absence of counter-evidence.
Information Booster:
1. Begging the Question: Assuming the truth of what you're supposed to prove (circular reasoning).
2. Fallacy of Accident: Applying a general rule to a specific case where it doesn't fit.
3. Appeal to Authority: Relying on the opinion of an authority rather than actual evidence.
