yes I believe in god... Though the Native American view of Creator is a bit different than the Muslim view.
evolution is a slow process, so lets say the heart was created firts (not neccessaraly a humans heart) then after some thousands of years blood came a long........what....a heart cannot work without blood. so just how in the world did th eheart survive?
Actually, "blood" came first. There are still a lot of critters out there that survive with 'blood' and no heart. Mostly simple worm like critters.
or anything for that matter, how did chance know that the heart does not work without blood, or that a heart nedds to be devided into 2 sides each with 2 sub groups? please explain that to me cos it seems it's either you are not paying attention or me.
Animals went from having what is called an "open" circulatory system... where the blood sort of just sloshes around via the movement of the animal.
Next you have animals that have a semi-closed circulatory system where there is a simple heart that is just one chamber and it just moves blood in one direction, usually against gravity.
Next you have a truly closed circulatory system, in this the heart is really becoming important. Usually you have a two chambered heart or a "one and a half" chambered heart.
By the time fish arrive you have a three chambered heart and a truly 'modern' circulatory system. Most animals have a three chambered heart. (fish, amphibians, most reptiles)
Alligators and crocs have a three and a half chambered heart. They can actually adjust how their heart beats to act as a three chambered heart or more like a four chambered heart. (they use this to switch between active high-oxygen behavior like hunting to low-oxygen behavior like resting at the bottom of a river... this is why they can stay under for so very long.)
Birds and mammals have finished what the crocs started and we have fully four chambered hearts.
So as you can see, there is a progression in the development of the heart, from none to simple and growing in complexity until you get to us.
Your only mistake was to look at the issue from the wrong direction...
