How does Buddhism explain the creation of everything (universe) How does Buddhism explain the creation of everything (universe). Did Buddhism faithfuls believe that universe had always been here and forever, and everything runs by cause-and-effect?

Did Buddha have any power of any kind to influence the universe, or it's just teaching? and if so, who rules the universe before Buddha's birth?
Buddhism says that the world has no discernible beginning.

That it runs by cause-and-effect.

That people are able to influence their own state, and have an effect on others.

And that you shouldn't spend too much attention on theoretical questions, such as "when did the universe begin?", because there are more important questions such as "how can we help to end suffering?"
