Of course there are external causes. Events are caused by your decisions and external causes. Very often external causes have more influence and they can also influence your future behaviour. When I said there is no free will, I meant that you can't influence your own decisions. In fact, according to this theory, "you" is just a product of your mind. Your brain just follows the law of physics and chemistry. Decisions are made by your synapses and are the result of your past experiences, genetics, hormones, logic, emotions and surroundings. So if there would be an all-knowing being that knows the exact state of the universe and how things interact, it could calculate the future. I don't define free will as being 100% the cause of an action. I would define it as the "freedom to do otherwise in the same circumstances". Bear in mind that this is just a theory. But even if it's wrong, the influence we have over our life might be smaller than we tend to think.
