Yes, the null Hypotheses cannot be stated TRUE or UNTRUE. But it must be completely get that we are never searching that: THIS IS NOT the aim of the NHST . . . What we want to know if there is sufficient evidence that the Null Hypothesis is unlike given data and confidence level (usually 95%). Situation leading to reject H0. If there is not sufficient evidence we must NOT MAKE ANY STATEMENT about the null  we failed to disprove  the ONLY thing we are allowed to conclude. How we can say that the null is accepted if we have any information about the difference between the null and the value of the test statistic we calculated? How??? It was R. Fisher established one century ago.
