Isnt the big bang theroy about the universe was one little thing the sive of peice of corn.wasnt there arock that travled at the speed of light nd hit this peice of corn.thatexploded and the universe coled and expaded and is still expandin today

Could you rephrase that?

The big bang theory is exactly that; a theory, as are all the other theories we are told about, including the creation theory.
By means of logical thinking we can question all theories. What went bang? If some 'thing' got so hot it exploded, where did the heat come from; for something to be defined as 'hot,' there must have been something cold too. Where did God come from? The list is endless.
If we can take the good things out of physics and science and improve the quality of life for everybody on earth, that is a good thing. If we can take the good things out of religion; love and understanding, that is a good thing. This is all we need, and maybe; just maybe, when we stop looking for these other answers - the answers may come to us.
