TOO BAD YOU STILL DON'T KNOW ANYTHING ABOUT THE WILL OF GOD. All you have are worthless/unsupported
claims.
STUPIDLY AND IGNORANTLY FALSE. Actual feral humans have existed --they are usually called "feral children", and you should study that subject sometime. It turns out they are the
default for Natural Human Development, and
can be a result of simple neglect, during their earliest years of life. What we call "normal" human development is actually a consequence of Nurture, not Nature. Appropriate Nurturing (and not needing the slightest mention of God) causes the brain to grow some extra processing power, for handling and manipulating abstractions. Human cultures are chock-full of abstractions, from language to writing to art to music and more --and feral children simply cannot process it the way average folks do.
ALSO, you are making a Standard Stupid Claim of Religions, that "morals" matter. NOPE! Not in the slightest! Simply because all things declared "moral" or "immoral" were
Arbitrarily declared to be such. Mere say-so, that is. Meanwhile, "ethics" has a chance of being non-arbitrary, totally rational, and Universally applicable (across all intelligent species and cultures throughout the entire Universe). God is not needed for anyone to be able to take an Objective perspective of things. Like selfishness. Consider this: Is the selfishness of Person A somehow inherently superior to the selfishness of Person B? No? Then the thing called "fairness" comes from declaring that Person A and Person B are equal to each other, in terms of having selfishness. And by extension, you can include Person C, Person D, and so on, until literally every person in existence is included. So now all you need, for a system of ethics, is a set of rules that encourage fairness, and don't favor any individual person's selfishness (or any group's selfishness) over other persons (or groups).
