The birth  of GOD is in your mind when you feel hopeless, miserable, scared and utterly defeated. Instead of succombing to depression and ending your life you PRAY and begin hoping that GOD will make everything right. Things get sorted out on its own with time or you may believe that GOD did set everything right. Whatever may be the case, the point is  YOU CREATED GOD AND PRAYED TO HIM AND GOT HOPE AND STRENGTH  TO CARRY ON. Thats it !  Thats the necessity of God and that is why I keep saying that the road to science and God never clashes. If whatever I said here boils down to  GOD IS A FIGMENT OF YOUR IMAGINATION THEN ITS A VERY NECESSARY PART OF YOUR IMAGINATION WITHOUT WHICH YOU CAN’T SURVIVE.
