>What if all the knowledge known to man existed within you
ALL is contained within your DNA. DNA has an open receptor which constantly adapts to new inputs, and contrary to previous belief this open receptor is affected instantaneously and not over thousands or millions of years. You are an unbroken chain of life over a billion years old, and every experience thereof. Back to the simplest microbe and algae, all knowledge in that unbroken chain of life is contained within you. Being able tap into that DNA memory is fleeting and impossible to predict or control, but possible to occur. The answer to your question is yes, your DNA contains every experience since the first spark of life.
