The Universe itself. The life on this planet. The fact that we don't burn up from being too close to the sun, or freeze from being too far from it. The fact that there is the correct mixture of oxygen in the air to keep us alive, that there is the right amount of water in our bodies, not too much, not too little. The water cycle in general. The fact that our bodily organs renew themselves every 7 years. The ways animals have a cycle of eating and being eaten. We were created, there is no doubt. The animals see in black and white, we could have lived with only seeing in black and white, but we were lovingly created seeing in color.
