It really frustrates me when people accept physical reality as the be-all end-all of existence. Just because chemical reactions take place in your body brain which keep it alive does not mean that you are your body or these chemical reactions. One thing science has never explained is consciousness itself, the origin of awareness and thought. What makes one think these things do originate in the brain/body? To me, this seems entirely illogical. Which is another thing to note, you cannot prove anything simply on the basis of logic or reason - one thing I've learned in my life is that there are many different kinds of logic and also even the most delusional things can be "proven" with some form of logical or rational thinking. Back to the point at hand, however, it confuses me how so many people seem to think your thoughts are chemical reactions in your brain. Just because there are activities in your brain which occur when you think does not mean that your thoughts are these activities. This is a concept which seems fairly obvious to me. Clearly physical matter is not thought. I mean hell - you're on the internet right now, and that can't be physically measured. I mean you can measure the bandwith it operates on, etc., but this information right here which we are all reading has absolutely NO physical basis. We are simply accessing it. Which is what I would argue our brain does; not create thought or experience but rather simply allows the physical body to access it. It is like a router between planes, connecting the realms spirit to material reality. Which brings up another way in which science is limited - by what our bodies can sense. Bees can see UV light and plenty of animals sense the magnetic fields of the Earth - who is to say that far more information exists at every moment which we simply have no means of measuring? Just because we have tools on our bodies for (at least) five senses does not mean these are the only stimuli/phenomena which exist.
Hopefully I've provided something interesting for everyone to think about... peace and love, in life and death.
