You still haven't shown proof that everything has a cause, though.
Sure I have.
You forget...
Everything is moving in the universe, because absolute zero is not quite attainable.
Movement means action.
Action means existence of reaction - Newton's 3rd Law.
This means that there is cause and effect in everything, which means there are programmed changes, not random mutations like Evolution theory says.
However, if absolute zero were attained somewhere in the universe, it wouldn't be in an evolving mutation. Absolute zero means no movement. No movement means no change... no mutation.
Evolution is a hoax.
However even if everything is in motion, what matters is the cause/causes of all the motions and you can't prove or show all the causes of all the motions, can you? True randomness exists, at least it's just the way quantum mechanics works. It may seem a bit unsatifactory to just have to accept the randomness, but remember that quantum mechanics is only a mathematical model - one that so far successfully describes the universe we see around us. All mathematical models are based on some assumptions, and the randomness in making measurements is one of these assumptions. It's possible that some deeper model will be developed one day, and this model will explain why the randomness occurs. However there is no such model at the moment, nor even a hint of one.
