Bryan says that only even numbers are composite

That's not exactly true. Odd numbers can be composite numbers too. For example 15 is a composite number because it has more than two factors.

Bryan is in error, and his statement suffers from a marked

paucity of veracity. Not only that ... it's also false.

9, 15, 21, 27, 33, 35, 39, 45, 49, 51, 55, 57, 63, and 69

are just a few of the odd composite numbers.

There are an infinite number of them.

It's true that except for ' 2 ', all other even numbers are composite,

and all other prime numbers are odd.

But that doesn't mean that odd numbers CAN'T be composite.
