Is someone else posting for you?
Anyway, yes, there has to be something else for there to be something new. I never once said that the laser came from nowhere. Obviously it needs a source of energy. Surrounding heat however has no real effect on it.
And for the second part, I never said anything about the sun. You're trying to make me out to be saying something that I didn't. And both sunlight and lasers heat up stuff, simple as that. One does it better than the other, but overall the main point still rings true.
