The reality of "Existence" is an extremely abstract idea to me ... just want opinions!?

Nothingness is not difficult to grasp if you simply think of an area of space where nothing exists. Focus on that section and block out everything that surrounds it then expand it mentally to include the entire universe. The problem is if that space was the entire universe then you would not be around to observe or imagine it. But what is the question here? Is nothing something? No. Nothing is the absolute void of everything both visible and invisible.
