I apologize for the length of my reply, but tried to make it as short as I could.
There is no logic or a carnal understanding when it comes to the Spiritual things of God. There is no logic or a carnal understanding when it comes to the Spiritual things of God as reasoning has to line up with what is already written in the Bible. Either you accept the Bible as being the word of God in all its parts, or you reject the whole as one can not pick and choose that of what they want to believe in part.
John 3:12 If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you of heavenly things?
Romans 8:5 For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit. 6 For to be carnally minded is death; but to be spiritually minded is life and peace. 7 Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be. 8 So then they that are in the flesh cannot please God.
You speak of reincarnation which is a philosophical concept of Greek philosophers like Pythagoras, Socrates and Plato. It's a central tenet/belief of all Indian religions namely Jainism, Buddhism, Hinduism, spiritism and todays New Age movement that reject the true God of all creation and His Son Christ Jesus.
There is no foundation for the concept of reincarnation found in what has already been written in scripture. In Luke 23:43 Jesus told the criminal that was being crucified beside Him"today you will be with me in paradise", meaning that the criminal believed that this was Christ as He hung on the cross and asked Him to remember him when Jesus comes into His Kingdom.
Hebrews 9:27 And as it is appointed unto men once to die, but after this the judgment:
Matthew 25:46 And these shall go away into everlasting punishment: but the righteous into life eternal.
John 5:28 Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice, 29 And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation.
Rev 20:11 And I saw a great white throne, and him that sat on it, from whose face the earth and the heaven fled away; and there was found no place for them. 12 And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works. 13 And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works. 14 And death and hell were cast into the lake of fire. This is the second death. 15 And whosoever was not found written in the book of life was cast into the lake of fire.
The belief in reincarnation is an ancient phenomenon that is unbiblical and according to scripture is rejected as a false teaching.
Genesis 2:7 And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.
Here dust + breath/spirit from God = a living soul. When the flesh dies physically it returns back to the dust of the ground and our spirit is preserved with God for final judgment.
Genesis 3:19 in the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return.
Ecc 12:7 then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.
We return to the dust of the ground when this physical body dies and our breath/spirit returns to God as we wait for Gods final judgment.
Matthew 10:28 And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell.
Our spirit can never die and is preserved until Gods final judgment on the last day when Christ returns, John 6:40.
Ruach, the Hebrew word for spirit means "breath" or "wind" as well as "spirit".
Ecc 9:5 for the living know that they shall die: but the dead know not any thing, neither have they any more a reward; for the memory of them is forgotten.
Psa 104:29 Thou hidest thy face, they are troubled: thou takest away their breath, they die, and return to their dust.
Dan 12:2 and many of them that sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt.
James 2:26 for as the body without the spirit is dead, so faith without works is dead also.
This body/flesh dies and deteriorates as it turns back to dust while in the ground. The breath/spirit goes back to God who gave it, Ecc 12:7. The soul which makes up the conscious part of ones being is that of thought, action and emotion. The spiritual nature of man regarded as immortal and separable from the body/flesh at death and susceptible to happiness or misery in a future state.
