what is death ?!

or maybe we should ask what happens after death ?

its a question no one knows the answer yet but I have invented a thought experiment that may helps to understand the true essence of death : 

" Imagine in future you can create an exact copy of yourself , and transfer all your thoughts and brain activities instantaneously . in fact it’s a simultaneous copy of you with exactly the same thoughts in the same time . now what happens if one of you is killed ? how do you define death here ?! "

Understanding God through Self-Exploration ..

I think the most complex and incomprehensible thing in the world is human being . the human being itself consists of most fundamental and challenging concepts in philosophy and science . concepts such as : free will , consciousness , complexity , design , and so on ...

so the old quote "Understanding God through Self-Exploration" seems to be true !

Inability of our brain to understand science :

When you are child its impossible to comprehend some concepts in the world no matter how much you try  . also In history it was impossible for early human to understand some concepts .

fundamental concepts

How we really got to know fundamental sub atomic forces in the world ? because we got to know larger cause and affect system in our bigger world . If we never known the concept of distance , speed , and force in our bigger world how could we even understand the concept of those fundamental forces ? ex : we know electromagnetic force because It creates force and force make an object to travel in a certain distance , we can go on by asking what is distance then ?! . so if there was any other fundamental concepts in the world we would never got to know them ?!

a proof of god ?!

can we prove intelligent design by feeling of joy ?!

Ok we cannot define complexity as a proof for god because something is complex just because we said so . we cannot define complexity . .  but what we really understand and believe in is consciousness .  when we enjoy something like when having sex , we really feel good about it ! so that is what we can feel and understand . here we can see complexity of body for one goal : enjoyment . we can see how everything in body of female and male work precisely together to get the job done : joy of sex ! how there are many many neurons in the penis and vagina to give you all the feelings .. so this complexity is for a good perceivable goal .
