The mystery of life - NOT amateur radio

Once in a while I post a philosophical question on this blog. I am no philosopher!

When we die those of a religious persuasion believe in some kind of life after death.  Those without a religious belief tend to believe life ceases and we just cease to exist.

Now, all we know is how little we know. We can experience only through our senses. In the last 150 years we realise how easily we cannot rely on our senses. As an example think of quantum mechanics which can be very counter-intuitive. All we can be sure about is how little we know.

There are so many things that we simply do not understand and probably can never know or understand. Human consciousness is perhaps the ultimate mystery.

Something tells me there is so much we cannot know.
