Liber Abaci posed, and solved, a problem involving the growth of a population of rabbits based on idealized assumptions. The solution, generation by generation, was a sequence of numbers later known as Fibonacci numbers. Although Fibonacci's Liber Abaci contains the earliest known description of the sequence outside of India, the sequence had been noted by Indian mathematicians as early as the sixth century.[19][20][21][22]

In the Fibonacci sequence of numbers, each number is the sum of the previous two numbers. Fibonacci began the sequence not with 0, 1, 1, 2, as modern mathematicians do but with 1,1, 2, etc. He carried the calculation up to the thirteenth place (fourteenth in modern counting), that is 233, though another manuscript carries it to the next place: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377.[23][24] Fibonacci did not speak about the golden ratio as the limit of the ratio of consecutive numbers in this sequence.

Basically it is argued that these number sequences can be found in nature. But I think that just shows some natural patterns already noted in nature and then put in mathematical formula.In mathematics, the Fibonacci numbers are the numbers in the following integer sequence, called the Fibonacci sequence, and characterized by the fact that every number after the first two is the sum of the two preceding ones:[1][2]

1 , 1 , 2 , 3 , 5 , 8 , 13 , 21 , 34 , 55 , 89 , 144 , …

Often, especially in modern usage, the sequence is extended by one more initial term:

0 , 1 , 1 , 2 , 3 , 5 , 8 , 13 , 21 , 34 , 55 , 89 , 144 , …

The Fibonacci spiral: an approximation of the golden spiral created by drawing circular arcs connecting the opposite corners of squares in the Fibonacci tiling;[4] this one uses squares of sizes 1, 1, 2, 3, 5, 8, 13 and 21.

By definition, the first two numbers in the Fibonacci sequence are either 1 and 1, or 0 and 1, depending on the chosen starting point of the sequence, and each subsequent number is the sum of the previous two.

Here's a good answer I found in a google search:

What do you think?Now that it is demystified, does it provide evidence for God, the answer is no. Here is why:

1.Mathematics is merely a set of rules to be used as an analogy for reality. These rules have logical consequences, including patterns like the Fibonacci sequence. Because these rules were meant to mirror reality in the first place, it's no surprise that a consequence of the rules would be reflected in reality. This may be hard to grasp, but here is an analogy.

Latin was created as a communication method meant to represent reality on some level or another. The word "necabantur" means "they were killed" in Latin. And since murders do occur, it surely must mean that this coincidence, between Latin and reality, can't be coincidence. There must be a higher power involved!

This is why I don't think that the Fibonacci sequence proves that there is a God or divine creator.
