How did humans originate? The answer is there in reading books about evolution , brain science, cell biology . This tells you what a human is .
A human is just another animal a brain. The image below shows all vertebrates have the same brain structure and parts. They are more similar than that because each brain is composed of billions of neurons. a nueron is a nerve cell and are basically the same accross species even non-vertebrates like flies, insects.
A neuron in a fly , human, mouse , fish are the same . All animals evolved from a single eukaryotic cell. I am that cell changed over 2 billion years but really the same . a cell has no soul no afterlife, no reincarnation it's just a machine. a human has no soul, no afterlife no reincarnation a human is just a machine, i every human has at least 30 trillion of these eukaryotic cells. neurons are specialized type of eukaryotic cell.

They mapped the brain of a larval fruit fly . And surprise the fly brain is uncannily similar to Ai neural networks , showing a human is neural networks = fly = ai. ai will soon surpass the weak human brain.
Over 12 years, researchers mapped all of a larval fruit fly's brain, charting 3,016 neurons and 548,000 connections. It's big news for neuroscience.

The neurons are connected into neural networks in the brain. The pattern and weights between connections is what creates the sentience concsiousness perception etc. Chatgpt and ai also are neural networks . the weights to chatgpt can be numbers in a spreadsheet file. ai is much smarter than humans in many areas already for example can write a good essay in a second. imo an agi or human can also be reduced to numbers / weights on a spreadsheet.
imo a human is 30 trillion cells. 86 billion cells in the brain neurons simulate the illusion that a human is one big animal when in reality is 30 trillion cells joined together . and a human is just that first eukaryotic cell with added abominations over time like a brain that can create constant unbearable pain ( but they tell us that's so beautiful)
