no you can't you are not old enough, to observe something is to see it, show me one thing evolving and i'll believe in your religion of evolution,
you see things that you attribute to evolution, but you can't actually see something in the process of evolution, why do you think they gave up looking for the missing link, because it doesn't exist.
