First off, you said, "our existance, but until now no one knows the real and absolute answer," are you saying: people knew back then, but don't know now, or are you saying people don't know then, but know now. Your first sentence is very gramatically confusing because you used many contradictary phrases. Rigged our brains? If anything.. our brains just simply aren't evolved enough... I live on facts and logic... seems to be working out so far for me. Even if there was a creator that built us and then "rigged our brains" to not see the underlying truth. Who cares? As a human whole, we aren't even doing anything. If "God", or something else more powerful created us, what for? -- these are rhetorical questions, for all you who can't tell. I'm saying don't worry about "who" created us or "how" we were created, we're here now, and we are doing nothing as a whole. We aren't serving anybody but ourselves.
On a slightly seperate topic, I find this higher power, mumbo jumbo, to be ridiculous. Just a curious question for you highly devoted religious people. What proof do you guys act upon, what sign has "God" ever showed you guys. Any definite proof at all? Or do you guys just hope that there is somebody watching after you? I just don't get how people can be so dependent on somebody who hasn't done anything for them as long as accurate history has been around.
