Can any one define the supreme being ?

Is there anything on the earth that can come into being without a creator. Is there anything that can come into being on the earth without some cause first. Why should it be any different with the whole universe? I do indeed believe there is a Creator. I believe that we ourselves are little bits of the Creator, and everything in the physical universe is also God. But ultimately it is still a great mystery. I think our greatest purpose in life is to ask questions like you have asked. Who is God? and Who are we? You should keep asking this question. The Universe will give answers in many different ways.

the lack of answers show that this is just something we don't know. there is no conclusive proof of any supreme being, but many people do believe in one. however there's no way of proving them. all we can do is make our own judgement, based on our own experiences and what we feel in our gut to be the truth.
