Sin originated in heaven with Satan's pride
Isaiah 14:12 How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations!
Isaiah 14:13 For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon the mount of the congregation, in the sides of the north:

Ezekiel 28:12 Son of man, take up a lamentation upon the king of Tyrus, and say unto him, Thus saith the Lord GOD; Thou sealest up the sum, full of wisdom, and perfect in beauty.
Ezekiel 28:13 Thou hast been in Eden the garden of God; every precious stone was thy covering, the sardius, topaz, and the diamond, the beryl, the onyx, and the jasper, the sapphire, the emerald, and the carbuncle, and gold: the workmanship of thy tabrets and of thy pipes was prepared in thee in the day that thou wast created.
Ezekiel 28:14 Thou art the anointed cherub that covereth; and I have set thee so: thou wast upon the holy mountain of God; thou hast walked up and down in the midst of the stones of fire.

Sin entered the world through Adam's disobedience (Genesis 3:1-24)
Romans 5:12 Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:
Romans 5:19 For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous.

Romans 7:25 I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin.
Man's sinful nature is described as:
Genesis 6:5 And GOD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
Jeremiah 17:9 The heart is deceitful above all things, and desperately wicked: who can know it?
Psalms 51:5 Behold, I was shapen in iniquity; and in sin did my mother conceive me.
Psalms 58:3 The wicked are estranged from the womb: they go astray as soon as they be born, speaking lies.
Proverbs 22:15 Foolishness is bound in the heart of a child; but the rod of correction shall drive it far from him.
Isaiah 64:6 But we are all as an unclean thing, and all our righteousnesses are as filthy rags; and we all do fade as a leaf; and our iniquities, like the wind, have taken us away.
Isaiah 53:6 All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid on him the iniquity of us all.
Why do people sin? Do we have to learn how to sin? Have you ever seen parents teach their children how to sin? If, like you keep insisting, that sin is not passed down genetically, why does God say all have sinned? Please don't say that not everybody sins and some are more wicked than others...because God is not a respector of persons.
1 John 1:8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
1 John 1:9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
1 John 1:10 If we say that we have not sinned, we make him a liar, and his word is not in us.
Why did Jesus Christ die on the cross and shed His sinless, precious, incorruptible blood for sinners?
1 Peter 1:18 Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation received by tradition from your fathers;
