Are you serious!!!! Have you ever thought that without battery or the use of any other fuel (except for food) How this human body is working ? Have you ever realised or felt your breath when you are in deep sleep ?...What i mean is apart from books and thesis there are common sense incidents that are a solid proof of existence of the god!!!...It's just that we have a habit of finding logic in each and every thing so we think have everything is happening just because another thing happened right before it..which compelled this thing to happen...Can't we think like this that every thing is happening by the grace of god ?
