DNA Proves Existence of a Designer

[pocaracas]

No, science definintely does not know why or how we have consciousness. There are neuroscientists all over the world working on solving the mystery of it right now.  And yours is also an argument of ignorance, just so we are on the same page with the type of discussion we are having.

If I may interject....

Would you say that a dog has consciousness?
How about a cat?
A chimp?
A bonobo?
An elephant?
An octopus?
A dolphin?
A whale?
A mouse?
A house fly?

What is consciousness?
How does it apply to humans, but not to most (or all) other animals?

Those neurologists look at all these and more animals and, within the limits of our ability to offer their thinking, attribute a spectrum of complexity of thought, of awareness of self and the world around... a spectrum of consciousness.
But you seem to imply that consciousness is an "all or nothing" deal. Either you have human-like consciousness, or you have nothing. Am I right?
If this were so, then I agree that we'd need to ask why that is...
But it's not. So there is no why.... And the how becomes a simple matter of complexity of certain structures of the brain.
And how did those structures evolve into what we see today? Here, since were taking about quite long time scales and actual brains of previous species have long decompress, we must speculate, based on the spectrum of brains we do see today and how they fit with brain sizes from what fossils we have from those previous species.

On the one hand, we have educated guesses, getting validated by computer modeling.
On the other, we have the next stage after myth, which was itself the next stage after folklore and tradition: god did it.

If you understand the history of the concept of god and evolution, then you understand that first there were men, already possessing a consciousness, and those men conjured up a rudimentary concept of god to help explain the world around them, the transition from life to death and to help ease the pain over lost loved ones. No god is actually required, but those people end up embracing the concept and believing it to be true.

If there was indeed a god behind consciousness itself, then let it come forward in the timeless fashion which you claim it has. Let all humans (those who feel the need to explain to other humans things about god) be quiet. Let god do the explaining and, if it fails at that task, let it remain the mental construct, the psychological crutch it has always been.
