When the universe needs something, a desire is instilled to discover, invent or create it. If one person who is called upon to do the actual discovering, inventing or creating doesn't complete it in a timely manner, another or others are called upon to complete the work.
There are streams of consciousness in the universe. When someone discovers, invents or creates something, often someone else discovers, invents or creates something similar and often at the same or nearly the same time.
The first peace, which is the most important, is that which comes within the souls of people when they realize their relationship, their oneness with the universe and all its powers, and when they realize that at the center of the universe dwells the Great Spirit, and that this center is really everywhere, it is within each of us.
It is known that are an infinite number of worlds, simply because there are an infinite amount of space for them to be in. However not every one of them is inhabited. Any finite number divided by infinity is as near nothing as makes no odds, so the average population of all the planets in the universe can be said to be zero. From this it follows that the population of the whole universe is also zero, and that any people you may meet from time to time are merely products of a deranged imagination.
