What and who is God?our imagination or something else,I just cant find!
One way to help address this question is to read about scientists or theological apologeticists say about who God is. Rather than try to search the inside of you own brain for the answers or ask your peers opinions, take a look at the thoughts of geniuses who have written their understanding down for us. Three that come readily to mind are Albert Einstein, Louis Pasteur and C.S. Lewis. Einstein, of course us the physicist who developed relativity and was a professed believer in God. Pasteur was a scientist noted developing the pasteurization process that eliminates germs and is famously noted for having said that there is a God-shaped vacuum in out hearts that only God can fill. C.S. Lewis was a classicalist and professor at Cambridge and Oxford and is most famous for writing the Narnia stories, allegories of Christian truths, theology, and experience. Lewis also wrote Miracles and God in the Dock. Lewis also wrote his autobiography detailing his conversion from atheism to Christianity, Surprised by Joy. Francis Schaeffer is the theologian apologeticist behind Shaeffer Institute in Switzerland and author of True Spirituality.
God is supposed to be a supreme and ethereal, being whose main characteristics are that he is a) omnipresent, b)omniscient, and c)omnipotent. This means that he is everywhere, knows everything, and can do anything. The idea of a deity has existed in every major culture and through every time period. Whenever humans experience an event to which there is no explanation, the tendency is to attribute its cause to something otherworldly which is equally hard to explain as in a way to "balance out" what is real and what is not; what could be and what may be.
However, the only way to "find" God, it is said, is to "search within your heart", which basically means that you need to want to believe in something upon which you will base your trust, and go to for support and reflection. The other stuff is just mere religion and religions are created by men. Hence, you can still believe in a "god" without having necessarily to follow a specific religion.
Soren Kierkegaard, Danish theologian and philosopher, whose philosophical work is concerned with how one lives as a "single individual" with personal choice and commitment, stated that one must take "a leap of faith" regarding God's existence. The existence of Yahweh, "I am Who am," is empiricially impossible to prove; it is faith that drives people's beliefs in Deity.
There has been many a heated discussion on this site and throughout the world, but nothing yet has been scientifically proven. It is solely people's "leap of faith" that assures them of God's existence. From where this "leap of faith" comes is also undertermined. Some find it when they marvel at the wonders of Nature; some find it when they join a religious group, some find it in times of challenge to their souls....
The answer to the question depends largely on which religion you choose to believe. Almost all faiths that believe in God hold Him to be a higher power or a great deity. Of course, any religion is simply faith. We can neither prove nor disprove the existence of God. I may believe that I experience God in my life but this is my personal belief and not a scientific fact. Some might say that makes God part of my imagination while others would argue that He is far more. In truth, it is all faith.
It's no wonder you can't find out since this is something that no one can ever know for certain in this life time. Everything about God or the gods or spirits is simply a matter of opinion. Clearly, human beings as a species have an innate need to believe in the supernatural. However, this does not prove either that God is real or that God comes only from our imaginations. This is something that can never be proven in this life.
Not all peoples regard their deities as supreme, omnipresent, omniscient, or omnipotent. Many peoples, indeed probably most peoples over human history have perceived spiritual forces as either immanent in nature (which could be construed as omnipresent) or dwelling within specific structures or creatures.
I agree with post 3 except the religion part of it. Any Divine religion would make it easy to understand God. The the examples can be seen in Quran and I just quote 2 of these revealed 1400 years ago on an a person born in a dessert with no schooling.
1. The creation and stages of development of embryo in the womb
We made you, then why did you not acknowledge it ass the truth? Have you considered your life germ? Do you create that or We the Creators? Quran 56:57-59
And that it is He who has made the pairs - male and female. From the sperm when it is placed. Quran 53:45-46
And then We made the sperm into a clot, and We made clot into a lump of flesh, then we made lump of flesh into bones, and We dressed the bones with flesh, then we evolved him into another make. Therefore blessed be God, the Best to make. Quran 23:14
2. Recovery of body of Pharaoh after drowning in sea
"... Therefore We will rescue thy corpse people are most this day that thou mayest be a sign him who succeed thee." But most people are heedless of our signs. Quran 10:92
These two event have been proved by scientist to be true. and as God says:
Falsehood comes not to it (Quran) from before or from behind it. It is a sending down from (the) Wise, Praised (one). Quran 41:42
But still we do not believe in God and have questions like: "What an who is God?"
