For the historical record - *every* ancient religion did blood sacrifices until the time of Christ. Christ’s atonement ended the need for them among those Jews and Gentiles who accepted that belief; hence Christianity is the first religion without blood atonement.
When we lived in Nepal, the Hindus did a once yearly blood sacrifice and spread blood, not just on an altar somewhere, but on everything that moved - including taxis! And if there was a special need, a chicken would be sacrificed occasionally at other times.
Further comment: should the Jews rebuild their Temple (as the orthodox Jews and dispensationals believe they should), they will also begin blood sacrifices again.
