It's more of an open question. While we cannot use the scientific method to evaluate truth and even less so prove it in the mathematical sense with pure abstract reasoning without any wolrdly evidence, there could still be truths (in a weak sense of the word), at least for humans. Because as humans our morals are primarily based on our feelings/instincts/neurochemsitry/etc and those are highly similar (and of course there are exceptions and deviations such as psychopaths) across the world. Depending on our terminal goal as a civilization or society if humans really wanted to we could try and build some "axioms" of morals and build up other political and cultural truths from there.
