GOD

We suppose- gods as Supernatural beings who may be able to conceal and reveal themselves for their own purposes, as  in the tales  or as described in holy books. In addition, according to concepts of God, God is not part of the natural order, but the ultimate creator of nature and of the scientific laws.Since God (of the kind to which the arguments relate) is neither an entity in the universe nor a mathematical object, it is not obvious what kinds of arguments/proofs are relevant to God's existence. Even if the concept of scientific proof were not problematic, the fact that there is no conclusive scientific proof of the existence, or non-existence, of God.If we cannot reduce talk about God to anything else, or replace it, or prove it false, then perhaps God is as real as anything else. Here on Earth planet people are who are believers and people who do not believe in god's existence but for own sake we have to believe in god's existence to lead a calm and peaceful -purposeful life. As on the other side negativity rules which create only negativity as its product then stress, anxiety and other mental illness, will overpower as a result. 
If we are part of HIS creation then there might be a creator so You just have to believe:

1. God is the greatest conceivable being.
2. It is greater to exist than not to exist.
3. Therefore, God exists.
4. The VEDANTA PHILOSOPHY  insist on law of karma as proof of god. A human karmic acts as merits and demerits. That is why some people in this world are seen happy while some in misery,some are rich while some are poor,some are healthy while some are ill .Some physiological questions like why we are on earth? where we will go after death and what is the purpose of life. 
5. That religious beliefs may recruit cognitive mechanisms in order to satisfy these questions Psychologists observe that the majority of humans often ask existential questions such as "why we are here" and whether life has purpose.
6.  Some psychologists have posited that religious beliefs may recruit cognitive mechanisms in order to satisfy these questions. William James  emphasized the inner religious struggle between melancholy and happiness, and pointed to trance as a cognitive mechanism.
7.  Sigmund Freud  stressed fear and pain, the need for a powerful parental figure, the obsessional nature of ritual , and the hypnotic state a community can induce as contributing factors to the psychology of religion.
8. Pascal Boyer's  "Religion Explained" (2002), based in part on his anthropological field work, treats belief in God as the result of the brain's tendency towards agency detection. Boyer suggests that, because of evolutionary pressures, humans err on the side of attributing agency where there isn't any.
9.  In Boyer's view, belief in supernatural entities spreads and becomes culturally fixed because of their memorability. The concept of 'minimally counter intuitive' beings that differ from the ordinary in a small number of ways (such as being invisible, able to fly, or having access to strategic and otherwise secret information) leave a lasting impression that spreads through word-of-mouth.
10. Scott Atran's "In Gods We Trust: The Evolutionary Landscape of Religion" (2002) makes a similar argument and adds examination of the socially coordinating aspects of shared belief.
11.  In "Minds and Gods: The Cognitive Foundations of Religion," Todd Tremlin follows Boyer in arguing that universal human cognitive process naturally produces the concept of the supernatural. Tremlin contends that an agency detection device (ADD) and a theory of mind module (ToMM) lead humans to suspect an agent behind every event. Natural events for which there is no obvious agent may be attributed to God (c.f. Act of God).
12.  HE(GOD) says, "You will seek me and find me; when you seek me with all your heart, I will be found by you." If God does exist, would I want to know him? YES.
13. See what god has perfectly created,Sun,air and earth at proper and perfect state suitable for human beings and other species on earth. Magnetic field of planets  and distance and all other gifts for our use as water with unique chemical properties,human brain and D.N.A. the human cell like this: CGTGTGACTCGCTCCTGAT and so on. There are three billion of these letters in every human cell! just like you can program your phone to beep for specific reasons, DNA instructs the cell. DNA is a three-billion-lettered program telling the cell to act in a certain way. It is a full instruction manual. God does not force us to believe in him, though he could. Instead, he has provided sufficient proof of his existence for us to willingly respond to him.God wants to be known. He created us with the intention that we would know him. He has surrounded us with evidence of himself and he keeps the question of his existence squarely before us.
14. None but god can do wonders in this world. Has any one other than god has created beautiful human body,we do made robots but they are't beautiful as gods creation is.Man has tried to copy but never succeeded.
