Every theory (including Darwin’s) primarily proves someone has to design a theory; every product primarily proves someone has to design it. When Neil Armstrong and Buzz Aldrin landed on the moon it primarily proved intelligence of many people had to design that moon-mission.
1) If every machine primarily proves someone designed it, then a much more complex, wonderful, and living machine with reproductive feature would mean the same: someone with corresponding ability, of higher energy, designed it because effect explains the cause just like harvest explains the sowing (whether you saw sowing or not). Science shows human body is like a complex machinery with many departments/systems (such as respiratory, digestive, cardiovascular/circulatory, renal/urinary, endocrine, nervous, musculoskeletal, integumentary/exocrine, lymphatic/immune, reproductive etc.) made up of at least 94 elements. The brain, of course, is the crown jewel of our nervous system. “The average human brain has about 100 billion neurons (or nerve cells) and many more neuroglia (or glial cells) which serve to support and protect the neurons. Each neuron may be connected to up to 10,000 other neurons, passing signals to each other via as many as 1,000 trillion synaptic connections.” (http://www.human-memory.net/brain_neurons.html). Even to count them at the rate of one per second we need millions of years. And that’s still not the end of the matter. What’s relevant is how many ways each cell can connect with the others.
2) And this is everybody’s experience: when something spiritual enters, body [in the womb] starts functioning, and when it exits body stops functioning, which means something not physical, a spirit factor, is more important than body parts! That is why we sense that complete whole is more complete than just the sum of its parts, as the word “holistic” being defined: “The view that an organic or integrated whole has a reality independent of and greater than the sum of its parts.” (Webster’s Unabridged Dictionary) That means there is an invisible spirit entity that hold all the parts, organs and body systems together and that make me feel I am constitutionally whole, because of which I know that I am more than this body, something of higher energy. It is too obvious that something other than physical should be at work because even when we are sleeping and daydreaming, internal activity is nonstop. No wonder Yoshinori Ohsumi, Nobel Laureate in Physiology and Medicine, said in his acceptance lecture in December 2016: “Life is an equilibrium state between synthesis and degradation of proteins.” In similar vein, French physiologist, Claude Bernard, wrote: “Stability of internal environment (in the body) is the condition for free and independent life.” Words such as, systems, coordination, connecting, equilibrium, synthesis, stability, design… all point to the work of something higher and spiritual. That means, under the Process of Elimination, one has to answer to the primary question (Who am I?): “I am not elements that make up my body; I am not this body, nor the mind, nor the intellect, nor a set of memories, but I am conscious energy that cannot be created nor destroyed.” Simply put, I am a spiritual entity that uses this physical body as my vehicle.
3) This is what even our very name—human being too implies. The word human is from humus [Latin] which denotes soil, and being is all about essence/spirit of a person. Thus a human being is described as spirit using body as its vehicle; and spirituality is to live according to this knowledge. The highest state of spirituality is at the level of just being, living according to one’s true identity, with no ignorance, no prejudice, no complex (superior or inferior). One’s normal state is joy. A person in this state of joy is in harmony within and without by just being aware of the present moment, which attracts good relationship towards him. His life is simple—he learns from the past, plans for the future but lives in/enjoys the present.
