GOD IS ENERGY ! & UNIVERSAL INTELLIGENCE !
First I will explain you by the means of Proof by Contradiction...
Suppose either GOD does not exist or GOD is not self created.
We are sure that nothing in the world can be self created....
First of all, how did you (as well as me) come in to this world?
If your answer is "Reproduction", then, how did the human race ever originate?????
If you trace back, you can find that all the living organisms in the world are simply huge aggregation of a vast quantity of cells.
Cells are the basic building block of Life. They are the functional basic unit of life.
Cells contain the basic organic and inorganic matter that constitute the life- namely, the nucleus, ribosome, DNA, etc.
But, how are cells created?
The Miller-Urey experiment suggests that that conditions on the primitive Earth may have favored chemical reactions that synthesized some amino acids and other organic compounds from inorganic precursors. Phospholipids spontaneously form lipid bilayers, the basic structure of a cell membrane.
But, from where did the lipids and amino acids come from?
Life as we know it today synthesizes proteins, which are polymers of amino acids using instructions encoded by cellular genes—which are polymers of deoxyribonucleic acid (DNA). Protein synthesis also entails intermediary ribonucleic acid (RNA) polymers.
Ribonucleic acid (RNA) is a biologically important type of molecule that consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate
Ribonucleic acid (RNA) is capable of both storing genetic information and catalyzing chemical reactions. Hence, it is the earliest self-replicating molecule ever discovered. Without RNA, proteins could never be made.
Most scientists have adopted the hypothesis that because DNA and proteins function together so intimately, it's unlikely that they arose independently. Therefore, many scientists consider the possibility that the first life was based on the DNA-protein intermediary: RNA.
Thus, RNA formed the basic block for the term "LIFE".
But, how did RNA Come into this world? Where from did the so called inorganic or organic come?
Essentially from the molecules!!
But, where from the molecules form? Atoms!!
What is the source of atoms????? Subatomic Particles!!
But, where did they come from?
If they can not be self created, then how did they come?
Ofcourse due to the ENERGY!!
Many scientists believe that Universe came into the existence due to a "Big bang"
Our universe is thought to have begun as an infinitesimally small, infinitely hot, infinitely dense, something - a singularity.
After its initial appearance, it apparently inflated (the "Big Bang"), expanded and cooled, going from very, very small and very, very hot, to the size and temperature of our current universe.
All is well till now?
But, what constituted the SINGULARITY?
It is purely a ball of Energy!!!
The Energy got converted into matter that has resulted in all the things we see now!!
"Energy can never be created nor be destroyed but, it can be converted from one form into another"
Thus, by law of conservation of mass and energy, the total Quantity should remain constant.
Hence, this proves that the net quantity of Matter and Energy prevailing in the Universe should be constant. This implies that NO ORGANISM OR EVEN AN ATOM CAN EVER SELF CREATE ITSELF!!!!
All is well till now......
But, the biggest Question before us.......................
WHERE DID THE ENERGY COME FROM?
What is its source????
If Energy can not be created, then how did it come?
That "ENERGY" is the GOD..
The Cosmological Argument for Existence of GOD:
The cosmological argument is the argument that the existence of the world or universe is strong evidence for the existence of a God who created it.
(1) Everything that exists has a cause of its existence.
(2) The universe exists.
(3) The universe has a cause of its existence.
(4) If the universe has a cause of its existence, then that cause is God.
(5) God exists.
