The society you grew up in (I take it you grew up in U.S.) incorporated Moral Laws of Judaism into it's onw social structure.
If this is the case, why then have only 3-4 of the Ten Commandments ever been laws? That's less than half, which is weird if they're supposed to be the basis of our legal system.
The only laws that are shared between our system and the Ten Commandments are those laws that are so generally useful that they pop up in the moral codes of every culture that survives.
There was very few atheists about 300 years ago, you know.
Not among the founding fathers. Largely they were of the opinion that God took no actions in this world except to create it, if even that.
Koran (Islamic bible) says that if someone will come to your house and tries to convert you, you must take out your sword and chop the head of the imbasel (not in these exact words). Whanna scientifically prove that they are wrong?
(I think the word you wanted was "infidel", not "imbicile".) The Christian Old Testament says that Thou Shall Keep No Other Gods but Me, and perscribes death to any who break those commandments. What's better about that?
You think that you are smart enough, because all your life, since your birth, you were spoon fed God's morals through filter of a Social Behaviour based on His word.
That largely ignores the success of many cultures with moral codes with no connection to Judeo-Christian belief.
You will realize that all these things around you, are made of exactly the same thing. QUARKS.
If you're trying to set up an analogy of unity or something, you need to know that there's no less than six types ("flavors") of quark.
