First of all, my grand mom going to disown me if she comes to know that i am an atheist and about my ideology about god. I feel there is higher energy but not like we read in mythological texts and manuscripts. Religion and practices are ways to give direction to mankind, set examples and differentiate between good & evil. Being a science student , I generally find myself relating such practices with science and logic. In the end, I beleive everything leads to math, especially 0 and 1
"God" is just a catch-all term for the truths that science hasn't yet uncovered. But there is science and maths there, underlying everything. There is no celestial overseer.
You can see this is true by looking at long timescales. God is shrinking over time, and will eventually disappear.
Thousands of years ago, God was everything. The Sun was God, Nature was God, Rain and Thunder were God.
Over time these became natural phenomena, but God was still there, albeit a smaller God: God moved the Sun and Moon around the Earth.
And then came Copernicus, Galileo et al - and God shrunk again. The Earth wasn't the centre of the universe, the sun was one star amongst many, the moon a simple ball of rock in continuous freefall around our own ball of rock, as we are in freefall around the sun.
Okay, but God still created the Animals, and still created Man, his chosen creature... and then came Darwin. Evolution by natural selection, with overwhelming evidence. God shrinks again.
God is simply the name for the science that we don't yet understand.
The point of what you are saying is that complexity of the universe is beyond mankind at present.
Consider the science that we don't know much of anything about, the science of the soul/spirit and the science of the medium that we call empty space.
Why would anyone think that there isn't a science of the identity and soul/spirit of God? We can't even understand these two things - our personal identity and our soul/spirit - but we use them all the time. We are the essence of what they are. But we can't objectively get a handle on them scientifically.
Everything that we do in life, exists in a much greater doing in nature around us. Yet it is nature that is profoundly greater than what we do. In fact, everything we do exists as a thing in nature. In other words, the Doer of nature is as far greater than we are, as the doings of nature are far greater than our doings.
God is the basis for everything. He isn't the basis because we might apply that kind of basis in our lives. He is the basis because He exists as the basis. Proof is in the fact that we die, but nature goes on.
