It can't be Holy Almighty Creator who needs people to sacrifice anything (of his own creatures o_O) to him.
Bible is just a part of BIG ancient writing. When you find some other sources of Babbilon or Sumerians you can find some unexpected features like:
- Jehovah had a wife called Astarte
- She left him to Baal (Baal isn't name actually. Some kind of title)
- Same deeds in different books are counted as Jehovah deeds and Satan's deeds.
I found that Jehovah wasn't good God. He was cruel, vengeful and suffer from complexes creature. He wasn't Almighty. But he wanted people to count him as Almighty. And our world wasn't created by him.
Sorry if my words harms anybody. But for me this ancient times aren't Holy times. Just history.
I think that Nord (Aryan, Scandinavian, Slavic), Sumerian, Indian and American Indian mythology are much closer to truth about world's creation. They describe something similar to primary blast and non-material eternal everywhere-being-god.
Anyway, truth is out there. I think that truth isn't in religion. It is in knowing and awareness of processes that are around us anywhere and in anytime.
P.S.
Psalm 82:6 I said, “You are gods, And all of you are sons of the Most High.
