If clairvoyants DO exist, it's likely that humans barely have the capacity to perform such feats since humans in general are still young and have a lot of evolving to do; at our current level we barely have the intellectual capacity to understand how the solar system works or to be able to comprehend the sheer amount of stars in the universe or the size of our galaxy let alone something such as clairvoyance or anything mystical.

Humanity has potential for greatness provided we one day evolve out of our selfish primal instincts and learn to accept each other's differences rather than judge them and learn that knowledge is more powerful than money.

We still have a long way to go.
