Some verbs cannot be used in the progressive tenses. They are called non-action verbs.
Non-action verbs indicate state, sense, desire, possession, or opinion. The most common
non-action verbs are:

be*
seem
appear*
(existence)

look*
sound*
smell*
taste*
feel*
(senses)

like
want
prefer
love*
(desire)

have*
own
possess
(possession)

think*
believe
consider*
(opinion)

Note the usage in the following sentences:

(Correct)

form of the verb is used.
