Take a few amino acids, throw in some water carbohydrate and fat for nourishment and see what happens. – of course not that simple but take a look at this zygote become a tadpole.
So the leader DNA, now directs the rest of the one cell to divide multiple into different types of cells and reorganize the shape, create neurons, heart muscle etc!

Does the soul enter the body after the body is formed, half way through or when the zygote is formed?
Cells multiply. You can create an artificial ear from a stem cell. Is there life or soul in there?
Are these chemical reactions giving the illusion of life? Illusion of soul?
So you may ask five different people and get 6 different answers. Each one can be dogmatic about theur answer. No matter how foolish. Why? It would be difficult to disprove?
So who really knows the answer? If there is a soul or spirit then one who has fukl experience of it would know! So if you don’t know or you have doubts then you have not experienced your spiritual self. The Atman. Or even the soul.
Does the soul remember? How? There was no brain structure from one body to the other
Simplest way out of this headache is to deny existence of the soul. This is all humbug. Insane fantasy. Signs of a weak mind who needs strength from a figurative thing called God
Other way out is experience it. Meditate. Throw away your books and blogs. But do it properly. Not in some self delusional, self approved style which you imagine is the right way or something that you learned from a bigger fool than you – a fake Guru
