No one knows anything about anything, they just put symbols into things and say that the symbols are the things. So, individuals know allot about the symbolical identity of everything. Well, let's admit that none of us knows a single thing, shall we? Words don't replace objects, they just serve as reference points. So, why all talk about something other then the topic? Because their terminology in their mind explains the topic to 100%, while you can't understand it for you got a different set of terms to things.
Most humans today have no clue what the heck they are actually saying. Their reference point refers to other reference points which leads to a chain that includes allot of symbols, but no actual things … just language. A wise one try to attempt to deliver constructs, but in long range. It causes people to replace things with their words … and then Gods came.
