> You can use science to verify ethical statements
No, you can't. (And not just in the sense that science falsifies rather than verifies.)
Ethical/moral statements always have a value component that is empirically unfalsifiable. They sometimes also have a falsifiable factual premise that, along with a set of value premises, supports a conclusion. Science can falsify the fact component, and sufficient failute to falsify can justify belief in the false component, but cannot falsify or (by failing to falsify) justify the value component, and therefore cannot justify the statement as a whole.
