To be - это глагол состояния (stative/non-Continious verb). У таких глаголов, чтобы показать на длительность процесса, Continious не используется, т.к. длительность уже заложена в смысл глагола.
Вместе с тем, иногда to be используется в Continious, но не тогда, когда у него значение "быть/существовать", а, например, "действовать/вести себя". Например, если Пол ведет себя глупо, ему можно сказать:
Paul, you're being silly!
