Yes, the body without breath is dead. I did say breath or life in general. Look it up, you don't need to take just my words.
Why don't you explain how an animal can have a spirit if they are made from the earth and not born of God?
Again, I'll answer with scripture " Who knows the spirit of man that goes upward, and the spirit of the beast that goes downward toward the earth?" Ecc. 3:21. Answer: God. You can try to twist Gods' Word to fit your theology all you want, but it says what it says. BTW, I have looked it up, and you know it, and in addition to breath it also says BY RESEMBLANCE SPIRIT, but you NEVER acknowledge it. God says, IN HIS WORD, that man and beasts have spirits. Only mans spirit is made in the image and after the likeness(resemblance) of God. Parentheses mine. " God is a Spirit:.... " Jn 4:23. Question, does God, who is Spirit, have eyes, fingers, hands, feet, ears, etc., etc.? Then so do I, spiritually. A king had sent a search party of soldiers looking for Elisha in Dothan. " Therefore sent he thither horses, and chariots, and a great host: and they came by night, and compassed the city about. And when the servant of the man of God was risen early, and gone forth, behold, an host compassed the city both with horses and chariots, And his servant said unto him, Alas, my master! how shall we do? And he answered, fear not: for they that be with us are more than they that be with them. And Elisha prayed, and said, Lord, I pray Thee OPEN HIS EYES, THAT HE MAY SEE. And the Lord opened the eyes of the young man and he saw: and behold, the mountain was full of horses and chariots of fire round about Elisha." 2 Kings 6:14-17. Now, the servant saw the horses, chariots and the great host surrounding the city, sent by the King. Elisha prayed that God would open his eyes so that he could see. What eyes? His spiritual eyes, so that he could see into the spiritual dimension and see the chariots of fire. When Jesus said in Matt. 11:15 " He that hath ears to hear, let him hear." Everyone had ears, except the deaf, so what ears was He talking about? Spiritual ears, for He said " :The Words that I speak unto you they are spirit and they are life." John 6:63. Whether acknowledged or not, there is a spiritual man in all of mankind, the part of us made in the image and after the likeness of God, it just, because of the sin of Adam, was lessened and the soul became more prominent, following, or being led by, the dictates of the lusts of a fleshly mindset. God opens up our spiritual ears to receive His spiritual Words. He opened mine several times until, as a twelve yr. old, I responded. I thank Him for His longsuffering with me, and because His Word says " The Lord is not slack concerning His promise, as some count slackness; but is longsuffering to us-ward, NOT WILLING THAT ANY SHOULD PERISH, but that ALL should come to repentance." 2 Peter 3:9. Since Gods' will is that none perish, then ALL have to have opportunity to repent. Faith comes by hearing, so God, according to His will that none perish, has to open up our spiritual ears at one time or another, so that ALL have opportunity to hear, spiritually.
