How to see if there is an afterlife in life from a scientific point of view?

As for past lives, I have been thinking about the soul when I was young, but I can't think of anything to justify myself. But I thought of a way at that time. Let's talk about it today Think of it as a joke for the time being!

We know that in our cognition, life is made up of cells! (Not to mention viruses) are divided into single-celled organisms and multicellular organisms!

A single cell has only instinct, swallowing, excreting and reproducing. But multicellular creatures are intelligent and have something beyond instinct!

However, the wisdom of different species is still different, and most wisdom is only a little higher than instinct!

So how did wisdom come from?

Every cell stores a substance, will it affect the intelligence of living things? I will call it "spirit" for the time being!

A single cell, a spirit with only one unit, can only have some basic instincts of life! With the increase of cells, multicellular creatures will have more spirit and instinct, but they still have no wisdom!

Spirit is like the cpu of a computer. Although you have enough running memory, there is no supporting software. You can only play the true colors of your calculation-calculation is the instinct of life!

Then when a creature has an organ, it is equivalent to software; With a brain, it is equivalent to an operating system, and there will be wisdom!

Spirit is a substance that we can't see or touch, but it exists. Its quantity is fixed! The birth and growth of life will absorb the spirit! Finally, death will bring the soul back to this world!

Life is unevenly distributed, and the spirit in space is naturally uneven! That's why there are outstanding people

Having said that, it is still limited to a limited level, which makes people really stumble! Now I begin to explain what the subject said about past lives!

Spirit can make cells "calculate", so spirit may also "store" some information! Generally, this kind of information is an impressive life memory, so it will be "stored" in the spirit. When life dies and the spirit dissipates between heaven and earth, the stored information will be erased! If this information is stored deep enough, after his death, the information in the spiritual body will not dissipate immediately like other shallow spirits, but will be very slow!

So when a creature has a brain and a large number of spirits with the same serial number (that is, spirits that dissipate after the death of the same person! ), that is equivalent to past lives! There will be this kind of consciousness in the brain, triggering programs in dreams or familiar places to wake up related past lives! It's just that this past life appeared in the form of a dream and a momentary thought!

Then, in my last life, you were not alone in your last life, but many souls. When a large number of spirits with the same serial number are absorbed by you, you have a complete logical fragment and become a memory of past lives! And many messy spirits will also become part of their dreams under the arrangement of their own brains!

We may get many people's past lives, but this kind of memory is only a few impressive things! There may be no previous life, because you didn't absorb the spirit of the same person's memory about the same thing!
