Because it is lying. I can see that all scientific theory which describes in terms of things being chosen is sidelined. I can see widespread rejection of subjectivity, atheism coupled with regarding love and hate as electrochemical processes in the brain. I can see that knowledge of good and evil provides a sham feeling of absolute confidence, while normally we are not very confident about anything.
So then you want to leave the possibility open for good and evil in the future to be fact is lying. You want to enjoy sham feelings of absolute confidence from your factual certainly about what is good and evil together with your evolution theory conspirators.
You could also have said, maybe in the future science will evaporate and it will all be religion. Not that I support that, but you could just as well have said that. But you didn't, you said it will all be science. You also simply reject my explanation of how subjectivity works, without argument. So it means you are against opinion.
