Believers or non-believers in the basic god/God concept, kept in mind as a possibility you might hope for or not, can be right by science or ethics
I'd discourage conservative belief stances as I would conservative social stances as matters of misinformation and needless harm. Ethics dictate harm would by unjustified for a possibility--it would be arbitrary--sadism and murder. And kept in mind as a possibility beyond what science determines it wouldn't make for a reason to change the findings of science.
I would then just add that you don't need to not believe in god/God to live by the things listed, either--to be a nice ethical person up to speed on things
And, whichever your choice, try to be friends and not 'centric or intolerant either way. 'Centric intolerance has caused the most harm by believers or non-believers.
