This is very interesting.
I find it amazing how such lifeless things can create something like a human through chemical reactions. How it responds to light and sends signals to the brain which then decides how to react to them.
How emotions such as surprise can cause reflexes such as blinking.
But then again there must be some sort of intelligence?
All these atoms have come together for some sort of reason. It can't just be chemical reactions that lead these atoms to form and perform actions. It can't just be chemical reactions that forces all the species in nature to reproduce, to make more copies of itself without a clear purpose? To seek out food and water, to grow towards the light, to continue being what we call 'alive'. To want to care for a baby that might not even be it's own (Saw that in cross-species altruism thread). To pass down some important memories (such as avoid this predator or go to the other side of the south pole just to reproduce with all the other penguins without any given purpose) through DNA into their offspring.
If all of these are just chemical reactions then there must be no such thing as life? It's hard to believe as I sit here with the ability to see my monitor, to move my fingers across my keyboard and to smell all the aromas around me and respond to them, think about them that all of these are just the combined work of everything within my body including all the bacteria who are also just a combination of more chemical reactions.
Are we then any different to the futuristic androids we hope to create in the near future?
And then when something kills us such as a disease all these chemical reactions just end? We are dead, yet all those chemicals are still there, all those atoms and structures but they do not continue to react in any way.
One more thing that I don't understand is how the brain stores a consciousness/memory. Is it again just chemicals in different areas/states in the brain that allow us to remember things?
