Laws, societies and democracies are built on the very foundation of this principle
Laws are what the majority of people agree are boundaries that people shouldn't cross and we take people to task and stop them doing it if they do.
Morals are based exactly the same way, they are simply what the collective agrees are acceptable
If you want to make the claim that God granted people inalienable rights the first thing you need to do is prove the existance of God, without doing that you have zero claim.
God was created by man, not the other way around...
