Firstly, thank you.
Secondly, well, I'm under the opinion that we simply have no need for it to survive if we're purely a product of natural processes. Animals have survived billions of years longer than humans without the type of morality we have, they have survived well without art, without music, without this higher-level of intelligence, etc., and are STILL thriving, albeit, we don't drive them extinct.
In other words, what we can do as humans vastly surpasses what's necessary for survival by a long shot. This why I believe humans are made in God's image, and why animals are not.
To get to my point, these things are a gift from God...a gift designed to make life more than just survivable, but to make life enjoyable and worth living, and gives us an obligation to God and fellow man regardless of kinship, etc, and gives us purpose.
Strip all this away, and we'd survive just fine, but life wouldn't be the same.
