Which pagan religion is native to Europe?

[Darth Whatsit]

It's difficult to say precisely; although given how religious practice is shaped by geography, the practices associated with spirits and deities associated with water or woods would probably be a good example of indigenous religion.

The core of European paganism has been ancestor worship and a constant vision of pessimism about the present and the future due to decaying values. This doesn't mean that pessimism is part of the European spirituality but rather an ambition towards the higher, as we value our ancestors/gods as being beyond good and bad; not perfect but still more than we are.

It's all shamanic Satanic filth, child-sacrificing evilness. Pure garbage. Thank God he delivered us from that bondage!

first off there is no evidence of child sacrifice in any native European pagan religion, there is evidence of this evil however in Semitic pre-abrahamic religions. In Celtic paganism for example, though we know little of it do to the exaggerations of Romans, and the Celts being mostly illiterate do to the druidic belief that memory is more powerful then writing, we know that sacrifices were rare, and when they did occur, they were mostly criminals restoring their honor by sacrifice or volunteers who wanted to send messages to the gods. The only reason roman sources say that these were more common in say Inis Mona during the invasion of Britain, was the sheer desperateness of their situation.
In Germanic paganism, human sacrifice was also rare, and tended to be the death of noblemen and great warriors by hanging and being stabbed with a spear to appease Odin to win a war. Thor however, the god most people worshiped, appeared to need no sacrifices except that of animals. The one source by Adam of Bremen of 9 men being sacrificed was likely to make the pagans look more barbaric, as all other sources deny such claims, and Adams accounts of germanic folklore is only loosely like actual norse myth.
