Uhm... Neanderthals are extinct.
You donÂ’t understand:
Solecki’s pioneering studies of the Shanidar skeletons and their burials suggested complex socialization skills. From pollen found in one of the Shanidar graves, Solecki hypothesized that flowers had been buried with the Neanderthal dead—until then, such burials had been associated only with Cro-Magnons, the earliest known H. sapiens in Europe. “Someone in the last Ice Age,” Solecki wrote, “must have ranged the mountainside in the mournful task of collecting flowers for the dead.” Furthermore, Solecki continued, “It seems logical to us today that pretty things like flowers should be placed with the cherished dead, but to find flowers in a Neanderthal burial that took place about 60,000 years ago is another matter.” Skeletons showed evidence of injuries tended and healed—indications that the sick and wounded had been cared for.

That Neanderthals are extinct isn’t the point, what is the point is that hominids began the process of contriving religious beliefs from the very beginning of human evolutionary history, that man in fact invented religion and made it a fundamental social component. And as human society and civilization developed and evolved, so too did religion develop and evolve, where man eventually created deities, and later created ‘god.’
I've never disputed that humans invented religion. Again, for about the millionth time, religion is a manifestation of human spiritual connection, our ability to connect spiritually. Try to get this point through that Cro-Magnon-thick cranium of yours. I'm getting tired of typing it.
Neanderthal spirituality is rare and isolated. Most discovery of Neanderthal remains show no signs of any type of spiritual behavior, and honestly, flowers for the dead or caring for the sick is rudimentary spirituality at best. As I correctly stated, it is believed the Neanderthals were 'mimicking' what they observed in homo sapien counterparts as their populations declined... a typical behavior in natural selection. They were largely non-spiritual, but it wouldn't matter if there had been Neanderthal POPES! They are of the same genus as humans, many argue they are the same species.
Back on the subject of spirituality vs. religion... while there are signs that humans invented religion, there is no sign that humans invented spiritual connection. In fact, that contradicts nature, science, biological behavior in animals, and Darwin's natural selection. I have explained how, I shouldn't have to keep re-typing it over and over again. We find ZERO evidence that any living organism has EVER invented something imaginary to cope with fears of death or the unknown. Now humans have certainly set some precedents for being the first at numerous things, this particular attribute could not have been retained unless it had benefit to the survival of the species. Had it been 'figment of imagination' it would have been long discarded as a behavioral attribute. Certainly, when thousands and millions of the species were being slaughtered and killed for practicing the behavior. OR... Darwin was completely WRONG!
