No they haven't. Consciousness implies a degree of self awareness. Humans have consciousness. Dogs have consciousness. Bacteria do not. You don't have consciousness without animal life. Rocks and trees aren't conscious. The individual neurons and glial cells of your brain aren't conscious by themselves, but the network they form is. It is an emergent property of the collective network.
Notice how where ever your brain goes your consciousness seems to be there? You don't have consciousness without a brain present (don't invoke OBEs or spirits - neither has been proven, lets stick to facts). You can swap out any other organ in the human body and the personality remains intact. Let me repeat that - you can replace ANY ORGAN IN THE BODY BUT THE BRAIN and the personality of a person remains the same. Brain transplants are not viable. Why? Limited technology for a start, we can't play with nerves like that (yet). All of your long term memories are located in the
hippocampus (we know this because people with damage to this area of the brain can no longer form permanent memories). Your personality is the emergent property of the collection of memories and experiences that are stored and retrieved from that lump of pink matter in your skull.
Our brains are pattern recognition masters. So good infact, we see patterns that aren't even there. We're extraordinarily good at seeing faces in clouds, mountains, sidewalks, anything really. We've all played that game as kids 'what can you see in the clouds?'.
Music is no different. Our brains hear 'patterns in noise' that we call music. There are literally thousands, perhaps tens of thousands of combinations of two or more notes to play on a guitar, called a chord. However, only 200-400 of these can be played without sounding like absolute shit. This has to do with the resonance frequency that the strings vibrate at with respect to the other strings, as well as whatever came before or after it in the musical piece. Pacing also has a part to play. Typically you don't get high pitched notes played in a long drawn out fashion, and you don't make a guitar solo out of low pitched notes either.
I don't see what this has anything to do with consciousness however. Music is a beautiful thing, but that doesn't make it god-given, esoteric, or spiritual in any way. It's just mathematics in sound-waves.
I do accept that love exists because I have felt it in the past, as I would hope we all have at some point or another. Such a universal concept is hard to disprove, as there are very few individuals (sociopaths for a start) that are incapable of love or have never felt it. Whether it's love for your parents, your partner or your mythical religious icon makes no difference.
As for evidence, I read a study a year or two ago of putting people into an MRI, and having them view pictures or think intensely about the people they love most in their lives, and another group of people were told to think intensely about their love for their god or gods. Both sets of MRIs showed the same area of the brain lighting up.
We're no longer living in a time when 'prove you loved your father' is a philosophical road block or conversation stopper such as 'do you see the colour red the same way I see it?'. We live in a time where I can show you the same physiological effects of 'love' on separate people in an MRI.
Furthermore, love is a by-product of our mammalian evolution. If you actually care to learn more about this, research attachment theory in a psychology journal.
Perform several reality checks. Pretty good indication there. Unless you're invoking Descartes '
evil demon' scenario in which I'm going to say you're being asinine.
