So what do you believe, where did we come from, a big bang? Which is actually quite possible, except there was a banger that initiated the bang. The universe have been expanding ever since the beginning of time.
And why is " morally wrong to kill? What if I like to eat human flesh like say a lion in Africa likes to hunt antelope for his meal. Why can't I hunt human flesh for my meal? Why is human life any more significant than the antelopes life? We as animals are all going to perish, why is the human life I want to hunt and eat in this example anymore valuable than the antelopes life? Who made up this entity of morality? Who's concept or idea is this which we call morality? Please do tell.
The preservation of the human species suggests that it's unfavorable to kill our own species and consume them.
