Often individuals will say things such as "I'm only human", or "it's human nature to do that". Mostly about negative actions. There is one adjective which is used positively, and that is "humane".
There is so much conflicting information about where we came from. Some say we were created by a god, others that we evolved from monkeys. Others that we are a mishmash of alien and Earthly DNA material.
And, our nature, what it means to be one of us, a human being, is riddled with cultural, religious and social programming.
