Billions and billions of years ago(actually around 4.5 billion years) this chunk of rock we live on was formed. Composed of an atmosphere of mainly hydrogen and helium and a rocky surface full of volcanic activity. It wasn't suited for life. But being the perfect distance away from the sun. It was primed to hold life. As the hydrogen and helium left our atmosphere(being too light to stay bound to our gravity), rocks in the crust of the earth began to release oxygen and other gasses trapped in them, As the Sun shined upon the Earth and through the water it gave life to tiny bacteria underneath the water. Bacteria that is the ancestor to all plants on the face of the planet. That bacteria evolved and spread out from the water onto land and then further into land. Evolving further to develop roots which in turn formed soil. Then to follow flowers and fruits. A perfect beginning.
Different bacteria formed to develop into creatures, after the perfect energy source(plants and fruits) were formed. Along with the perfect gas, oxygen. Some of these creatures moved out of the oceans and evolved on land. They were the were the ancestors of the dinosaurs, birds, fish, insects and last the mammals. The perfect conditions had to take place for this to happen. Monkey's had to evolve and slowly change to what we are today. The sun had to be the right distance away. There had to be food to sustain life. There had to be oxygen for us to breathe. This all had to be perfect for us to even have a fighting chance to start.
You may think your body is imperfect. Like, I am too fat or I am short. Those maybe true, but inside is the epitome of perfection. You are a complex individual. Yes, even your mind , but . no one cares about your feelings in this tirade. Let's start with the oxygen you need to take in. Okay,.into the lungs it goes. You have two for optimal performance, but you can get by on one. Albeit not that greatly, The oxygen is transferred to your blood stream and back to your heart to be transported to all of your organs. The heart never stops(whilst you live). It beats and pumps like a perfectly tuned watch. Speeding and slowing as is needed without an external source programming it to do so. There is a myth that we only use 10% of our brain. Think about that. The brain consumes around 20% or our bodies resources. That is quite wasteful just to use 10% of your brain. It runs everything in your body through neurons, nerves and other chemical impulses. It tells your legs to move, your eyes to look, to grow, love and many other things. It even does such wondrous things as paralyze you and forces you to watch vivid images that sometimes fool you in believing what you see is real even with your eyes shut. Ah dreaming. No, unfortunately you use 100% of your brain. Perfection. You have organs that filter poisons and release chemicals to convert sugars and even release them when you need it. Two eyes for depth perception and peripheral vision and two ears for balance and hearing sound from every angle. A fighting chance to be perfect in our perfect world.
I know I have taken an optimistic view on the world. I know there is death pain and suffrage, There is crime and evil people and floods, earthquakes and other turmoil in the world, but it is easy to do that. It is easy to be cynical and note all the horrible things. It is hard to be to say all the good things. It is hard to be perfect. The world and all life on it wasn't easy to happen.We weren't all of the sudden here. That is too easy Species of all kinds struggled and lived and died even today they aren't making it. Several lanes of evolution dead ended and what you see today is what we have. In thousands of years maybe there will be something different. Again it will be something perfect.
Every atom in your body came from a star that exploded. And, the atoms
in your left hand probably came from a different star than your right
hand. It really is the most poetic thing I know about physics: You are
all stardust. You couldn’t be here if stars hadn’t exploded, because the
elements - the carbon, nitrogen, oxygen, iron, all the things that
matter for evolution and for life - weren’t created at the beginning of
time. They were created in the nuclear furnaces of stars, and the only
way for them to get into your body is if those stars were kind enough to
explode. So, forget Jesus. The stars died so that you could be here
