Well ... from a purely scientific standpoint, yes. Keeping in mind Einstein's famous E=MC2, once the heart stops beating, and those cells in our brains are no longer being fed extra energy in order to transform, they revert to being simply a large goopy mass of chemicals and elements, nothing more. The question no-one has of yet discovered though - Is it possible to re-create all those chemicals and elements and put them into exactly the same state as they were in YOU, and thereby create another you? Quantum Mechanics would suggest ... No.
Because you cannot, without some level of uncertainty, recreate the exact same configuration, so that it would take you an infinite number of tries to get the mixture "exactly" right. But that also begs the question, how many of those trillions of interconnected particles could you change, and have the outcome still be .. you? After all, our bodies are undergoing trillions of interactions every day, trillions of quantum changes every day, so how much has to be the same and how much can be different?
Which leads into Pagafyr's question ...
What is "life" ? At it's most basic form, life is those simple chemical reactions occurring in such a way that the molecule becomes increasingly more complex, but that requires two things = energy, and room to grow. But what happens when the molecule loses one or both of those? it stops "growing" and either stays static, or reverts to individual chemicals, In other words it dies. But if it gets fed more energy, and interacts with more chemicals it can continue to grow, until it reaches the limit of the locally available chemical interactions i.e. it runs out of room. So what does it do then?
Well here is where the "complex life" or self replicating part comes in. It splits itself in half, essentially reverting to a lesser evolved version of itself in order to regrow or recreate another fully evolved version.
So is that what "life" is? Is it the desire, the basic "emotion" of simply wanting continued existence? The question then becomes ...
Well, who ordered THAT!?!?!
Could it be that what we call "thought" doesn't actually occur within our bodies, but instead occurs in some other realm, some other dimension, and is only loosely linked to the chemical soup and meat bags we call bodies? Is there something or some ONE that "wants" to exist, and uses us as it's means to do so?
Looking out at the planets, and moons, the stars and nebula, the galaxies, or the whole universe, it looks strangely ... familiar. Almost like the representations that we see in images and videos of the "neural net" that is supposedly the human brain. So could it possibly be, that we are simply "neurons" or even perhaps simply the electrical signals or patterns themselves of a "brain" that is the entire universe? Are we nothing more than the thoughts and dreams of a "being" of such unimaginable complexity that we will never be able to truly comprehend it, and yet somehow, our existence still contributes to it's own search for meaning?
