If you ask a christian why Jesus(pbuh) need to die for the atonement of Sins

 If you ask a christian why Jesus(pbuh) need to die for the atonement of Sins, A christian will tell you that God born/incarnated as human was the only sinless flesh which can take away the sin of the world, only sinless flesh can take away the sins of the world.. OK, lets agree for the sake of arguments, that only the sacrifice of sinless flesh can take away the sin of world...
>> Now please tell us if we sacrifice a Goat for atonement of sins of world, what sin a goat has committed.?? is the flesh of a Goat not sinless.??
>> Now please tell us if we sacrifice a bull for atonement of sins of world, what sin a bull has committed.?? is the flesh of a bull not sinless.??
>> Now please tell us if we sacrifice a sheep for atonement of sins of world, what sin a sheep has committed.?? is the sheep of a Goat not sinless.??

Ok another point as we all understand from perspective Christianity that only jesus(pbuh) was sinless as every other child is born with original sin but only jesus(pbuh) wasnt born with a original sin..

>> Now please tell us if we sacrifice a Goat for atonement of sins of world, A goat has also born without original sin..??
>> Now please tell us if we sacrifice a bull for atonement of sins of world, A bull has also born without original sin..??
>> Now please tell us if we sacrifice a sheep for atonement of sins of world, A sheep has also born without original sin..??

If the sacrifice for atonement of sins for whole world, was all about a "sinless flesh" and born without "original sin" then we have goats, sheeps, bulls, etc, or was it about human flesh/born of a woman..?? show us where did God loved human sacrifice.?? where he demanded it.?? where he accepted it.?? where did he commanded it.??

2. We also see in bible that the sacrifice of human flesh is abomination in bible, to sacrifice of one who is born of a woman is abomination in bible, it is detestable to the God in bible, the sacrifice of human flesh/born of a women is a pagan ritual in bible done to pagan Gods and hated by God in bible.(Deuteronomy 12:29-31 to know how much God hated human sacrifice). How can then the God himself turned to pagan ritual, turned to something he hated, do you mean God of bible himself turned pagan
and turned to pagan ritual and sacrificed human flesh/born of women for the atonement of Sins.. The thing he hated, the sacrifice he hated, the ritual he hated, do you mean he so loved the sinners that he himself started loving these pagan ritual/sacrifice and himself turned to a thing which he declared a abomination before.??

3. We read in both Bible and Quran that the sacrifice which is loved by God is
===>> BIBLE
>>>> "The sacrifice acceptable to God is a broken spirit; a broken and contrite heart, O God, thou wilt not despise.(Psalm 51:17)"

>>>> "“I, the Lord, am the one speaking to you. Come, let’s discuss this. Even if your sins are as dark as red dye, that stain can be removed and you will be as pure as wool that is as white as snow. (Isaiah 1:18)"

>>>> "For thus says the high and lofty One who inhabits eternity, whose name is Holy: “I dwell in the high and holy place, and also with him who is of a contrite and humble spirit, to revive the spirit of the humble, and to revive the heart of the contrite. (Isaiah 57:15)"

>>>> "All these things my hand has made, and so all these things are mine, says the Lord. But this is the man to whom I will look, he that is humble and contrite in spirit, and trembles at my word. (Isaiah 66:2)"

>>> "“Submit to God and be at Peace with him; in this way prosperity will come to you. Accept instruction from his mouth and lay up his words in your heart. If you return to the Almighty, you will be restored ..." (Job 22:21-23)"

===>> QURAN

>>> Allah says in the Holy Quran Chapter 6 Surah Anaam verse 54:
When those come to you who believe in Our Signs, say: "Peace be on you! Your Lord had inscribed for Himself (the rule of) Mercy. Verily if any of you did evil in ignorance, and thereafter repented and amended (his conduct), Lo! He is Oft-Forgiving, Most Merciful."

>>>> "Allah says in the Holy Quran Chapter 39 Surah Zumur verses 53-54: (O Prophet) say: “O My servants who have wronged their own souls….Do not despair of Allah’s Mercy! Surely, Allah forgives all sins. He indeed is the All Forgiving, All Merciful. Return to your Lord and submit to Him before the scourge overtakes you; for then you may get no help from anywhere.”

>>> Allah says in the Holy Quran Chapter 3 Surah Ale Imraan verse 135-136: Allah likes such good people very much, who, if ever they commit a base deed or wrong their own soul by the commission of a sin, remember Allah instantly, and ask for forgiveness from Him for their shortcomings. For who, but Allah, can forgive sins? (And Allah loves those) who do not knowingly persist in the wrongs they did.These will be rewarded with forgiveness from Allah, and with Gardens beneath which canals flow, and they will reside therein forever! How excellent is the reward of those who do good deeds!
