Is Earth the only planet within our solar system or even the universe that yields life to sentient beings? This is a question one must ask when questioning the existence of extraterrestrial life. Taking into account that the universe vaster than I or anyone could possibly comprehend, I am a firm believer in the existence of extraterrestrial life

Extraterrestrial life is defined as life that may exist and originate outside our planet Earth. Its existence is currently hypothetical, meaning there has yet to be any evidence of extraterrestrial life that has been widely accepted by scientists. This includes the well over a million UFO reports since 1947. None of which can provide a scientifically credible physical artifact.

Even so, this doesn't alter my stand on extraterrestrial life. It's the sheer size of the universe that enables me to be confident in my beliefs. To put it into perspective, there are more stars in the universe than there are grains of sand on all the beaches of Earth.

In the last few years astronomers have gained the technology with which to discover planets around nearby stars and it's been discovered that most stars do have planets. This means that if there are 10,000,000,000,000,000 planets in the universe, it's very possible that 10,000,000,000 of these planets are capable of producing life. With statistics like this, even with a margin of error I find it hard to deny extraterrestrial life's inevitable existence.
