I don't need to prove God exists. The question wasn't "Is God real?" the question was "WHY does blood sacrifice bring any atonement for our sins?"
By asking this question it is already assumed that God is real and that Biblical answers are an option, since the Bible talks about God.
I'm glad I could help you understand that, we all need help sometimes.

"And without faith it is impossible to please God, because anyone who comes to him must believe that he exists and that he rewards those who earnestly seek him." Hebrews 11:6
