"...unicorns, leprechauns, supreme beings"

This falls under #5 "Argument from Personal Incredulity", #7 "Confusing the currently unexplained with the unexplainable", and #8 "False Continuum". At LEAST those three.

1.        Ad hominem An ad hominem argument is any that attempts to counter another's claims or conclusions by attacking the person, rather than addressing the argument itself. True believers will often commit this fallacy by countering the arguments of skeptics by stating that skeptics are closed minded. Skeptics, on the other hand, may fall into the trap of dismissing the claims of UFO believers, for example, by stating that people who believe in UFO's are crazy or stupid.

2. Ad ignorantum The argument from ignorance basically states that a specific belief is true because we don't know that it isn't true. Defenders of extrasensory perception, for example, will often overemphasize how much we do not know about the human brain. UFO proponents will often argue that an object sighted in the sky is unknown, and therefore it is an alien spacecraft.

3. Argument from authority Stating that a claim is true because a person or group of perceived authority says it is true. Often this argument is implied by emphasizing the many years of experience, or the formal degrees held by the individual making a specific claim. It is reasonable to give more credence to the claims of those with the proper background, education, and credentials, or to be suspicious of the claims of someone making authoritative statements in an area for which they cannot demonstrate expertise. But the truth of a claim should ultimately rest on logic and evidence, not the authority of the person promoting it. Another way this is seen from time to time is when the authority cited is cited for his/her brilliance, but not as it relates to the subject at hand; For instance: the Albert Einstein bumper sticker – "You Cannot Simultaneously Prevent And Prepare For War". It should be obvious, but doesn't always occur to one, that there is nothing about Einstein's particular genius that makes him more qualified (than the average Joe) to talk about geopolitics

4. Argument from final Consequences Such arguments (also called teleological) are based on a reversal of cause and effect, because they argue that something is caused by the ultimate effect that it has, or purpose that is serves. For example: God must exist, because otherwise life would have no meaning.

5. Argument from Personal Incredulity I cannot explain or understand this, therefore it cannot be true. Creationists are fond of arguing that they cannot imagine the complexity of life resulting from blind evolution, but that does not mean life did not evolve.

6. Confusing association with causation This is similar to the post-hoc fallacy in that it assumes cause and effect for two variables simply because they are correlated, although the relationship here is not strictly that of one variable following the other in time. This fallacy is often used to give a statistical correlation a causal interpretation. For example, during the 1990s both religious attendance and illegal drug use have been on the rise. It would be a fallacy to conclude that therefore, religious attendance causes illegal drug use. It is also possible that drug use leads to an increase in religious attendance, or that both drug use and religious attendance are increased by a third variable, such as an increase in societal unrest. It is also possible that both variables are independent of one another, and it is mere coincidence that they are both increasing at the same time. A corollary to this is the invocation of this logical fallacy to argue that an association does not represent causation; rather it is more accurate to say that correlation does not necessarily mean causation, but it can. Also, multiple independent correlations can point reliably to causation, and is a reasonable line of argument.

7. Confusing currently unexplained with unexplainable Because we do not currently have an adequate explanation for a phenomenon does not mean that it is forever unexplainable or that it therefore defies the laws of nature or requires a paranormal explanation.

8. False Continuum The idea that because there is no definitive demarcation line between two extremes, that the distinction between the extremes is not real or meaningful: It would be like saying that since there seems to be a fuzzy line between cults and religion, therefore the two are really the same thing.

9. False Dichotomy Arbitrarily reducing a set of many possibilities to only two. This is constantly seen in politics where only two "black and white" propositions are presented as the only possible solutions when there could, in reality, be any number of better solutions from an expanded pool of answers.

10. Inconsistency Applying criteria or rules to one belief, claim, argument, or position but not to others. For example, some consumer advocates argue that we need stronger regulation of prescription drugs to ensure their safety and effectiveness, but at the same time argue that medicinal herbs should be sold with no regulation for either safety or effectiveness. Of course, the corollary fallacy is the "But he/she did it first!", wherein an inconsistency in arbitration leads to the claim that the basis for one's "correctness" is that it exceeds, or at least matches a previous (but obviously wrong) action by another (see Tu quoque, below).

11. The Moving Goalpost A method of denial arbitrarily moving the criteria for "proof" or acceptance of said "proof" out of range of whatever evidence currently exists.

12. Non-Sequitur In Latin this term translates to "doesn't follow". This refers to an argument in which the conclusion does not necessarily follow from the premises. In other words, a logical connection is implied where none exists.

13. Post-hoc ergo propter hoc This fallacy follows the basic format of: A preceded B, therefore A caused B, and therefore assumes cause and effect for two events just because they are temporally related (the latin translates to "after this, therefore because of this").   If a fellow dies after eating green beans, it doesn't follow that the green beans were the cause of death.

14. Reductio ad absurdum These arguments assume that if an argument is valid, it necessarily means that the most extreme example of that argument must also be valid. A UFO enthusiast once argued that if I am skeptical about the existence of alien visitors, I must also be skeptical of the existence of the Great Wall of China, since I have not personally seen either. He therefore tried to take my skepticism to an absurd extreme in order to invalidate any skepticism.

15. Slippery Slope This logical fallacy is the argument that a position is not consistent or tenable because accepting the position means that the extreme of the position must also be accepted. But moderate positions do not necessarily lead down the slippery slope to the extreme.

16. Straw Man Arguing against a position which you create specifically to be easy to argue against, rather than the position actually held by those who oppose your point of view.

17. Special pleading, or ad-hoc reasoning This is a subtle fallacy which is often difficult to recognize. In essence, it is the arbitrary introduction of new elements into an argument in order to fix them so that they appear valid. A good example of this is the ad-hoc dismissal of negative test results. For example, one might point out that ESP has never been demonstrated under adequate test conditions, therefore ESP is not a genuine phenomenon. Defenders of ESP have attempted to counter this argument by introducing the arbitrary premise that ESP does not work in the presence of skeptics. This fallacy is often taken to ridiculous extremes, and more and more bizarre ad hoc elements are added to explain experimental failures or logical inconsistencies.

18. Tautology A tautology is an argument that utilizes circular reasoning, which means that the conclusion is also its own premise. The structure of such arguments is A=B therefore A=B, although the premise and conclusion might be formulated differently so it is not immediately apparent as such. For example, saying that therapeutic touch works because it manipulates the life force is a tautology because the definition of therapeutic touch is the alleged manipulation (without touching) of the life force.

19. Tu quoque Literally, you too. This is an attempt to justify wrong action because someone else also does it. "My evidence may be invalid, but so is yours."

20. Unstated Major Premise This fallacy occurs when one makes an argument which assumes a premise which is not explicitly stated. For example, arguing that we should label food products with their cholesterol content because Americans have high cholesterol assumes that: 1) cholesterol in food causes high serum cholesterol; 2) labeling will reduce consumption of cholesterol; and 3) that having a high serum cholesterol is unhealthy. This fallacy is also sometimes called begging the question.
