Dr. Eben Alexander's experience and many other people's similar experiences revealed the afterlife of human being. We can see a tip of an iceberg through these super-physical experiences.
Undoubtedly only a small amount of people have this kind of afterlife experiences. It often happens after a tragedy. I know a lady who saw people were rescuing her after a fatal car accident while she felt she was floating in the air.
The core is the soul. Soul exists without human body. Where is the soul from? Apparently the egg and sperm do not have soul like a human. Then a question rises here: When the soul enters the human body???
As described in this book, I Met My Son Before He Was Born, the soul enters human body just before the birth. It is a kind of shocking feeling when the soul entered the body. The consciousness started right after the body merged with the soul.
There are many books talking about afterlife. This is the only book I could find talking about the soul before the human was born and prelife.
Everyone experienced the soul infusion, but most majority of people just can not remember that moment before he/she was born. It is very possible you may be able to recall that original moment of your life after you read this book.
Go to mormon.org. Gao, you will find the question, "Where did I come from before this life?" answered there. I hope you find the answer you seek...I know that I lived before my earth life, and that I chose my earth family and life, because I needed to learn the lessons they had to teach me.
I knew there would be an anti mormon reply to my post as soon as I posted it. Your reply is your opinion...I have read the Book of Mormon numerous times, and each time my testimony of it grows. This book, Proof of Heaven, agrees with doctrine taught by the LDS church. The original poster of this thread wanted to know where to find information on the pre earth life. Our Church teaches that. I know it is true, because of the experiences I have had in my life. I will continue to live my life according to the dictates of my own conscience and allow you that same right. To save you some time, don't bother quoting all your anti references, I have read those...Fawn Brodie et al. I have found them to be distortions and half truths written by those who have axes to grind. There will come a time when we will know all there is to know. My prayer for you and all the other anti whatever's out there is that you find something in life to be for that will bring you the joy I have in my life through knowing Christ, my Savior. Being positive and happy about the choices i have made in my life leaves me no time to tear down someone else's choices. Have a blessed day.
