If you are going to make a statement like this, assert that it is true, and then say that there is no real evidence to support the claim/or that no knowledge about the subject is certain, then what the hell is the point of even bringing up such a thing?
...[warning, ad hominum ahead]...ANYONE could easily make an argument out of nothing; hell, statements like this only perpetuate ignorance.
"dude, god is real, I can't prove it to you, but it should be obvious"
Sound familiar? I think every one of us have heard it before - unfortuantely, this is exactly how your argument is coming across to me. Either back up your statements with research, or don't be taken seriously.
Edit: The reason I'm hounding for this is that this is an extremely huge claim you are making, that would completely shift cultural morality (legal positivistic sense/natural morality/religious based/ whatever) around the globe. So anyone who has any source for this, then please - share.
