This is one of the most interesting questions..

Why Do People Die ?????

People don’t die, the organic matter that makes us human, deteriorates & withers away & dies for this is the only way to maintain a well functioning ever continuing process :
To create, cultivate & then deteriorate & then again create !

Otherwise if everything becomes static then there would be just nothing in existence for nothing will be created to even deteriorate.

Thus, for any kind of continuity or infinity to be maintained, change is necessary & this is exactly what gives rise to the concept of time otherwise to think of no time is beyond our mind.

If we understand time & try to think about no time, our thoughts would die, they would not move, not be, they would vanish & extinguish & so would our experience of life !

This might seem difficult to comprehend but its true & does happen.

So, as long as there is life & as long as there is time, people will die & everything else will also die
Yes, with advancement in technology, a time would come when what we know as our memories & perhaps the mind would continue to survive & people would think that they are alive for it’s the mind which thinks, feels & knows life but there would hardly be life & still their metallic parts would get broken & junk & would deteriorate with time.

It would be a strange future & it would be a strange mankind .
Just few centuries from now, everything that we otherwise know as human life would undergo a massive transformation which is unimaginable by all means right now, even by the intelligent & wise.

This sort of humanity would perhaps inhabit other planets & spread to other areas of the universe from the most dry to the most wet to the extreme ice.

That would be a different era, a different civilization, a different time, a different life .

Would you & I & others be there ?
Maybe yes if the consciousness survives !
