There is existence outside Earth.

The Fibonacci sequence happens all throughout nature: flowers, pine cones, pineapple. The belief is that this is the most efficient way to grow and create life within the space provided. This is also seen in spiraling sea shells and our spiraling galaxy.

Pictures from the Andromeda Galaxy, our closest neighbor also follow this Fibonacci spiral. Would that not mean that life exists on each spiraling galaxy in some way, shape or form? Out of the eight planets in our solar system, Earth is crawling with all forms of life, and it is believed that Mars once flowed with lively water that may have helped organisms grow (if the planet weren't so close to the sun). I am certain that in the Andromeda Galaxy, at least one planet has rapidly-growing numbers of prokaryotes inhabiting it.
