Because with out a subject we would not know who/what does the action (verb).

The boy ate the cake. - We know the boy does the action of eat.

Sometimes sentences do not have subjects these are called imperative sentences. They are used for commands exclamations and warnings. But the subject is implied, it is you.

A complete sentence must have a subject (noun) and a predicate (verb). For example, "The bird flies in the sky." "The bird" is the subject of the sentence (bird is a noun) and "flies in the sky" is the predicate (flies is the verb). This is a complete sentence. "The mailman" is NOT a complete sentence because there is no predicate (I didn't tell you what the mailman did). Ask yourself "Who?" and "Did what?" and if you're able to answer both questions then you probably have a subject and a predicate, and therefore, a complete sentence.
