Consciousness is a hard problem for many neuroscientists and philosophers. Other brain scientists and philosophers don't consider consciousness a hard problem. To them, consciousness is just regular brain activity: firing neurons, electricity, and neurotransmitters.
To my mind, everything is a hard problem: consciousness, matter, electrons, and quarks, the Big Bang. Are there really tons of universes out there? Are we living in an explosion?
What is a rainbow? What does it consist of? Does a rainbow really exist if no one is there who sees it?
What is a magnetic field? What kind of substance is a magnetic field made of?
What is a thought? What are thoughts made of?
Do you have a brain, or is it the brain that has you? What difference does it make for you in your life?
