How Nature was able to understand what we need.

[ignoramus]

OP, if I asked you why do all meteors land in craters, you'd think I'm silly.

So would I. Meteors don't land at all, in any sense.

Asteroids then!

Bloody cosmology nazi!

Asteroids are a bit of an overkill. Why not go for meteorites?

Is that the diff? Ta..

So weird .. nature can't nature without understanding stuff.

This question may sound "dumb" for some people, but the fact is, there is no stupid question.

The fact is I didn't learn about the theory of Evolution in school because I grew up in a Muslim country where teaching Evolution for what it is, is next to impossible. The books about the theory are either banned, or people don't dare look for them (you think you guys in America have it bad, try to go where I grew up and let's see what you think after). I'm planning however on taking a class on Biology or Evolutionary Biology at some point during my undergraduate degree (thankfully now I live in a Western developed country). So what I know so far about the theory is mostly by documentaries and a few books here and there, but not enough to give me the full picture, and here comes my question.

How was nature able to "understand" or "determine" what a living being needed? For example, how was nature able to "decide" that this creature needed a better eye to catch the light? Why did it even know that this being required to figure out where the light is in the first place? I don't know if my question makes sense, or if there is a better way to word it, but in simpler terms, how did the creature with light senses was even able to know that there is a light out there, a light outside, how and why did it know that it needed sight in the first place? Does my question make sense?

Firstly I'm not an American nor have I ever been to America, nor would I with its backwards healthcare system.

Secondly. You have misunderstood what evolution is and the relation to the environment.
There is the puddle explanation.
Your idea is like looking at a puddle of water and saying "The water fits perfectly the shape of the hole, the water must have been carefully positioned and designed to fit exactly as it does"

The creature that is best suited to the environment reproduces more and over time become dominant eventually becoming different species.

Most don’t land either.

How was nature able to "understand" or "determine" what a living being needed

OP, Once you get your head around the fact that no intelligent cosmic overseer exists or needs to exist, the theory of evolution logically falls into place.
As does the fact that we are also made up of the most common elements in the universe. Nothing abnormal there.

In fact, the universe and everything in it acts exactly like one would if there was no divine intervention.

The question is Not “How was nature able to "understand" or "determine" what a living being needed”.

Nature until modern men understands nothing.

The question is “by what process that would naturally operate with or without living beings that living beings were brought into existence, and adjust their needs to live on what is available in nature”, and a subtler question is “to what degree and by what process living beings, once arisen and became part of nature, allowed nature to better provide for the needs of other living beings like themselves”

Get a closed container and half fill it with sand and pebbles of different sizes. Start shaking it, first quite vigorously and then progressively more gently until you are hardly shaking it at all. After a while you'll find that the smaller stones slip through the spaces in-between the larger stones, and the sand, made up of the smallest stones is at the bottom.

The container was not able to understand that the sand needed to be at the bottom, it was an undirected physical process that sorted the contents over time. Evolution is the same.
