That's way off the mark. Even our fingerprints are unique, never mind our brains. Even identical twins develop differently as they encounter different formative experiences.
An opinion and just your unwillingness to accept the things possible when there is no alternative or it cannot be proved.
We have twin in our family identical and they can even finish each others sentences.
They were born premature and if my sister had not been in hospital at the time she and the babies would have died.
My sister had been in hospital for back pain and rest. They took her for a scan but the twins were lay in a way they did not see the placenta bleeding. One twin already started to die but the other twin had her arms around her. Hugging her, five minutes after an all clear scan she started to bleed heavily and she was rushed by crash team into theatre and they were all saved.
The twins are very close they are closer than the other siblings and they sense when the other in danger or upset.
You totally misunderstood my point that us being separate people shows we have a soul. If the brain was what run the person and not the person/soul controlling the body. Then we would be robots. You missed the point and the fact we are not robots show the body is told what to do by the person within it.
The body does not just decide to walk and take us where we do not want to go.
