The correct answer is delusions.

Delusions refer to erroneous or unfounded beliefs that are fixed and firmly held by an individual despite a lack of clear evidence supporting these beliefs. In this instance, Delmar's beliefs are incorrect, yet he is strongly convinced of them despite an logic or clear evidence supporting his claims. Another form of delusion is believing that aliens roam Earth without any evidence supporting this belief.
