Toss a stone into the pond. The ripples aren't the stone. But like they move upon the face of the pond, even so their vibration might extend forever even if it is in only a tiny, tiny way.
The "essence" of a person is NOT his physical form alone. Emotion, spirit and thought extend beyond the physical. But even they are not the person, entirely. However, we know from people who have lost many parts of their physical body, that although the emotion, and spirit and mind may change from the loss, the emotion, and spirit and mind are still strongly the person... way more strongly than simply the physical.
It seems that the "metaphysical" parts of a person go on just like the vibes of the stone that is tossed into the water. And being way more complex than the stone waves, who knows what will happen to them? Certainly they are not the same as they were when they were held captive in the physical body.
You wanted an answer that didn't have a lot to do with God, directly, so there you have it. However, nobody can remove God from the equation, since He holds everything in place. So, consider what He says before you do something as disastrous as suicide.
Nicely written piece of prose there, I found it relaxing and pleasant to read even though I don't agree with it.
The problem with your theory is that the majority of a human being's "essence" or consciousness resides in the brain (perhaps some in the spinal cord, or other organs but the brain is where the real shit happens). If someone, for example, lost a limb in a car crash, their essence or consciousness hasn't been directly affected as long as their brain remains intact. If you start lobotomizing people, then their consciousness will become affected.
However, consider body heat. Body heat is energy that moves beyond the body. If you think that the vibrational energy of thought and emotion and spirit remain only in the body, you are missing a lot of science.
As for your analogy of "ripples in water", well it's a cute concept but it makes no sense in terms of consciousness. Our influences on the world certainly affect things in an outward, ripply, butterfly effect type of way, but we are not "experiencing" any of those influences in the same way we experience emotions or pain through our conscious brain. So it is a different thing entirely.
Never heard of EEG machines or CAT scans? Both of these show that you are speaking from a very ignorant premise.
If I throw a huge rock into the sea, which creates a tsunami 1000 miles away that kills and injures thousands of people, I am not conscious of their suffering. Yeah I would feel terrible if I heard it on the news the next day, but I'm not intrinsically linked to the people I killed by some sort of metaphysical waves.
However, you do not know that you are NOT subconsciously aware of these things. The subconscious mind protects the conscious mind, so it would not allow your conscious mind to feel these vibes, which would be minor, and confused as they reached you.
In addition, consider when you move to a new city. It takes a long time for people to get used to you being there. A lot of it includes sympathetic and empathetic vibes.
You are trying to cover up the knowledge that exists medically and physically all over the place, that our vibes continue on after death, even though they are in a changed form, and even though they are weaker (are they weaker?) than they might have been in the living body.
On topic, when you die you rot in the ground. The atoms and molecules that make up your body (which were created billions of years ago in multiple interstellar supernovae) are broken down by insects, bacteria, fungi and other strange creatures. The resulting chemicals are consumed by organisms, which prosper and grow, eventually making offspring of their own. These organisms will eventually die, rot, and the chemicals in their dead bodies will provide food for the next generation of plants and animals.
Now you are simply talking silly. Dead people are not people. They are dead people. There is a difference. That isn't you rotting in the ground. It is your remains. You don't even sound credible.
I think it's a beautiful concept personally.
Of course I don't know this for sure, but from what we know it seems like the most likely explanation. We will only know for sure when the time comes, but until then I'm gonna try and make the most of life on this (sometimes shitty) planet.
Finally. You don't know for sure. Understatement of everything you had to say.
Live on, in your sometimes shitty life. But learn to think a little.
I started to reply to your points, but then I realized not a single one made sense, or even had anything to do with what I said. So I gave up. We'll never agree anyway because you believe in a soul and a god 100%, and I don't, and I know that your stubborness prevents anyone from changing your views.
I will say your comment accusing me of ignorance made no sense - I know how EEG and CAT scans work, and they have nothing to do with life after death. CAT scans are especially irrelevant because they are basically X-rays - they output radiation and record what is reflected back. You could do a CAT scan on a teapot and it would still appear on the screen - does that mean the teapot has a soul?
EEGs are different, because they are measuring the electrical activity in the brain. And yes, some of this energy will certainly reach outside the brain. But that absolutely doesn't mean that we can use this energy in any useful way, and it certainly isn't evidence for a soul.
Your final paragraph just sums up your attitude - yes of course I don't know for sure, but NOR DO YOU! And you believe in some real crazy shit man!
The worst thing is, you think you're above everyone else with your "scientific proofs of god" etc, when you're actually just very indoctrinated, arrogant, and unwilling to change your mind about literally everything you believe. Open your mind a little, you might learn something!
