Question

Why is the Fibonacci sequence found everywhere?

Answer 1

Tl;dr: It is not found everywhere, it describes what is found everywhere.

The way our Universe works is pretty much „Growth“; Atoms „grow“ into Molecules, which grow into Matter, etc. Seeds grow into Trees, Babies grow into Adults, Tribes grow into People.

The way Growth works is always the same: replication.
So if you start with 2 of anything and start to grow a population you will first create an offspring of each pair and add it to the total population – 2 becomes 3, now with 3 you can create 2 pairs, so you get 2 offsprings and add them to the population – 3 becomes 5, which can make 3 pairs and so on.

At some point mathematicians observed this and quickly figured out a pattern. This pattern became the fibonacci sequence.

So in the end the sequence isn‘t something that we invented and happens to be found everywhere, but the other way around: we observed something that happens everywhere and found a way to describe it.

Hope this helps, and sorry for any error or bad wording, english isn‘t my first language.
