I swear I put the key on the table. I cannot explain to myself where it has gone. Only a ghost could explain its disappearance. But then I realised that the cat had stolen it. The theory of evolution on the species has no good explanations for the existence of certain organisms or biological phenomena in nature, therefore the evolution theory is wrong or incomplete. But could we not find an explanation in five or ten years?
The absence of an argument supporting a statement does not imply that no such argument exists or will be found in the future. An unexplained phenomena does not mean that it is unexplicable.
Stick with the dogma that all phenomena have explanations, even if they are currently unexplained.
Write down 5 examples where an unexplained phenomena could be interpreted as an inexplicable event.

Reliance on authority: pro and con
Everyone gets statements wrong from time to time. A professor might well be proven wrong by his student. And if a small child says that 1+1=2 and Einstein says it is not, then the small child is right. The truthfullness of a statement should never be judged by the authority of the proposer but only by the strength of the arguments supporting the statement.
However, if Jimmy has got his facts wrong several times and Jane has not, I will rather trust Jane on a future issue. And I rather trust the professor than the high school student to get his statements correct. Thus, a statement is more likely to be true if the proposer is viewed as an authority. Such a short-cut in thinking saves an enormous amount of thinking time but is not without risk.
The secret is to obessively disregard any authority when deciding on the truthfullness of a statement, but at the same time to develop an intuition on who you can trust to get their statement right, use their statements as working statements, and only later view the strength of the arguments supporting the statements.
Write down 10 aspects that makes someone an authority that you could trust.

Problems and Mysteries
We try to understand how things work by asking questions: Why does the moon circle around the earth? Why do men find younger women more attractive? Why does this politician get the most votes? Why does my neighbour have an affair? What is consciousness? Do we have freedom of mind?
Here is what Steven Pinker writes in How the Mind Works:
Write down 10 problems and 10 mysteries. Remember some questions might be mysteries for some, problems for others, or even answered.
Here is what Steven Pinker writes in How the Mind Works:
"The linguist Noam Chomsky once suggested that our ignorance can be divided into problems and mysteries. When we face a problem, we may not know its solution, but we have insight, increasing knowledge, an an inkling of what we are looking for. When we face a mystery, however, we can only stare in wonder and bewilderment, not knowing what an explanation would even look like."
