As humans are animals, it's pretty obvious that some behaviors will be similar between different animals. Other behaviors are completely different.
At least one gorilla who was taught sign language showed an awareness of her own death, and a curiosity about what happened then.
Our relatives, the Neanderthals, definitely believed in something "out there", a life beyond death, which is clear in their burial rituals.
Evidence of this "conscious perception and willpower of the human soul", please, and that it can only have come from YOUR god and none other, please. On my desk by Friday.
(Oh, and it ought to be "God-given", dearie. As it stands now, it looks like it's the God that is given conscious perception and willpower.)
