Tacitus wrote that ancient Germanics killed convicted criminals and tossed the bodies into the bogs or even drowned bodies in the bogs. Also, more recent forensic evidence suggest natural causes were the number one cause of death of the bog bodies. Also, natural infant mortality rates made live child sacrifices too dysgenic to have become a tradition for civilizations that lasted as long as the Canaanites.
By the way, many Romans were propagandists who lied about their enemies initially to rationalize and justify conquests only for later generations to backtrack a bit.
