"what if GOD described everything for us.and told us everything we need to know.then there would be nothing new for us to learn or discover."

Of what relevance is that? how is that evidence of anything?

"there also would be no need for science."
The god hypothesis works with any output. Therefore it isn't science.

"but where is the irevalence in making a grain of sand from nothing?"
It has nothing to do with whether the science we now have is correct.

"if that is too hard for every scientist in this world to accomplish using everything science has learned , "
That is irrelevant.

"then why not just make a single atom or a electron or a photon , make anything from nothing and then get back to me."
Argument from ignorance is invalid.

"fact is all of science put together cant make anything from nothing using nothing."
Nobody claims that scientists made the universe.

"so where did something come from?"
Science doesn't know and may never know. That doesn't mean we throw up our hands and put an end to questioning.

Nobody's asking you to disbelieve in god. What I'm saying is that God is irrelevant to science.
