Does God exists? Well, now that is a good question.

I think before we discuss this, we should know what God is? 'What is God'?

As humans view, God is a being/entity which is immortal, omnipotent, can create and destroy, has ability of telepathy, Psychokinesis and a lot more. In short God is all powerful who is beyond our realm .
With our limited thinking, we can't grasp the exact concept of the whole word 'God' as we can only understand/learn about what we see/feel. We haven't even understood perfectly how a human body works. Even though we know about a lot of things yet none has completely perfected in anything. Hence we are incapable of understanding what God is, as of now.

When it comes to science, I see God as a higher intelligence who have exceeded us in millions of light years in terms of technology, intelligence, capable of understanding how the universe works and surpassed all physical and mental capabilities. Higher intelligence as I said can be a being from another planet who has been around, way before our species was born on this planet.

However, I do know something very sure, there was something that triggered our whole existence because everything we see around us are well organized and placed in order. Flower petals in Fibonacci series is one such example.

So what is God to you? If we understand what God is, it is easier to know whether God exists or not or else the whole debate is useless.
