What is life?

Life is so complicated and so variable that its hard to define what really life is.? Our heart continuously pumps blood. Contracts and expands to provide life to our whole body. So as the life is in our body so it emanates from our heart. Then by movement of heart. Then by blood. So we can say conclusively as life is movement or movement is life. But we know that life life is in heart and this organ spreads life to whole body by expanding and contracting thus supplying blood to whole body and by this supply providing blood to whole body. So the centre of the life is heart. But the question remains unanswered that in heart from where the life came. Life came from another life from a human sperm which has the complete potential of developing a full body from a sperm and from this developed heart wich supplied life to whole body. But in that human from where the life came. Science presumed that perhaps some meteorites came which have had smallest living organisms as viruses which have had amino acids which began to organize and communicate thus organizing into more complex structures thus giving birth to more life and thus the process of replication started and life spread extensively on planet earth and now we have 2.5 million living organisms and species on planet earth approximately. This is a theory that perhaps life has propagated in this way. Because before 4 billion years we were not here to observe all this process. But one thing seems clear that perhaps life had came from heaven.
In religion we assume that Allah/God has said and life came into existence. And Allah is Alive so he has created life. Because life gives life. In Islamic religious book Quran it is said that He is alive and persistently living.
Some say that life started from a spark in the heart as in motorcycle a spark starts the Engine.
Life has some amazing and distinguisher features also. Life from scientific point of view organized and formulated from gases as hydrogen, oxygen, nitrogen. As these form necessary components of life as proteins, water and carbohydrates. These gases are found in universe abundantly. So from the deep rooted study of gaseous components we come to know that we are consolidated from the complex and organization and consolidation of gases found in universe abundantly following a set rules and processes.
Life has distinguished and amazing features also. Life body can feel. Smell. Touch. Taste. Think. Create. Differentiate. Move. And replicate and give birth to his alike species. Life has power. Life can see. Life has millions of forms. Religion tells us that this is the soul which gives life to our physical body because we see that once life is out from our body this body can never again acquire this. Because soul is life and soul is not in the body now. So body has no life now. Life is designed into  specific structures. So we come to the conclusion that life is created and given a specific form by a superpower which we call Allah/God.
Infact this is a magic, a miracle. So astonishing hugely and immense miracle which I have ever witnessed in my life. In fact life is so much complicated and we even don't know really from where it really had came from. Life needs suitable environment and circumstances to grow and replicate which are provided by nature. As light from sun. Air from atmosphere as oxygen. Water from earth a d from rivers. Every thing for life is already created to support life on planet earth. Possibly there are many other forms and kinds of life we dont know as universe s so immense and huge that we even dont know its width and length so we can say that universe is unlimited.
