There is at least one absolutely true statement which is the statement: "Every statement is either true or false." Thus there exist at least one absolute truth.
If that statement were
absolutely true, then it would itself either be true or false (as every statement would), which means it would be
both possibly true
and possibly false. However, an
absolute truth is
not possibly false. And since there would be at least one statement of which we could
not say that it is "either true or false," the statement "every statement is either true or false" would be false.
