Whether or not we are alone in the universe has always been a question for mankind. Numerous telescopes are currently being used to look for faraway planets with the right conditions for life. The world must have the proper composition of its atmosphere, liquid water, magnetic field, and other elements, as well as the proper size and distance from its star.
However, the size of the universe itself determines whether or not there is life elsewhere in the universe. If it is large enough, not only is there life elsewhere in the universe, but there are also numerous copies of you spread throughout it.
The distinction between the numbers one million and one billion is not well understood by many individuals. They appear to be very similar numbers at first glimpse, but 1 billion is significantly larger than 1 million. These figures convert into seconds, and 1 million seconds equals roughly 12 days. As opposed to this, 1 trillion seconds is 30,000 years and 1 billion seconds is 30 years. It was less than two weeks ago a million seconds ago. The European Union had only been established for a billion seconds, and neanderthals had just gone extinct for a trillion seconds.
You are an atomic being that takes up about 1 cubic meter of space. You are merely one of the many shapes that the atoms in the area you inhabit can take. There may be another individual, a dog, a cat, a small tree, a rock, a vacuum, etc. in this area. Atoms can arrange themselves in 10 to the 10th to the 70th different ways in the space you inhabit. (a 1 with 70 zeros in front of it).
This means that if you move 10 to the 10th to the 70th meters in a specific direction, you will begin to see repetitions of these 1 cubic meter volumes because you have seen every configuration that matter could take to arrange itself in this space during this entire distance.
The current approximation of the universe's size is (10^26 m3)^3, which is incredibly small when compared to 10 to the 10th to 70th meters.
This means that if the universe is large enough, life lives outside of Earth and that there are exact copies of you, everyone you know, and everyone who has ever lived throughout human history dispersed throughout the same universe. This is due to the fact that in a world big enough, all the ways matter can organize itself in a volume of 1 cubic meter will repeat many times. This implies that everything that is capable of existing will do so repeatedly.
In regard to this, the phrase "be the best version of yourself" gains new significance. So, get going and start working so that you can prove to any other versions of you that you are the greatest.
