This is by "design," not some random BS
Some "advanced" being was being "thoughtful" by gracing us with this anomaly, so why are you STILL an atheist?

Like ancient people, you are fixated on something akin to the idea that the solar system revolves around the Earth. Your belief is effectively that
the Earth revolves around humanity; that is, the Earth was created to please humanity as opposed to humanity adapting to the Earth.
What you fail to realize is that blue and green are subjective interpretations. For example, birds see much more detail than we are capable of
seeing. Their sight is more detailed, they see a broader range of colors, including florescent rays. They see colors we don't see. On some species,
the florescent color spots aid the birds to visually differentiate between the sexes. Compared to birds, we might as well all be red-green color
If God actually existed, he could be sued under Strict Products Liability for making a defective product that gets cancer and offers insufficient
protection against deadly diseases.
Please write "Because God said so on your exams at school." That would be hilarious.
Why the sky is blue?
The earth has a protective blanket of gases, water and dust called an atmosphere. The blue color of the sky is a result of sunlight passing through
and interacting with the atmosphere. If you look at sunlight through a prism, you will find that "white" sunlight is actually composed of a rainbow
As sunlight passes through the atmosphere, the atmosphere selectively filters blue light using a process called scattering. Selective scattering
(preferential scattering of one color of light over other colors) occurs when light scatters off particles that are much smaller than the wavelengths
of the colors. In the case of our primarily nitrogen filled atmosphere, the shorter wavelengths (blue) are scattered much more strongly than the
longer wavelengths (red). Thus, as sunlight passes through our atmosphere, blue light is preferentially scattered, and becomes visible to the eye.
Why are so many plants green?
Plants are green because they have a substance called chlorophyll in them. Understanding why chlorophyll is green requires a little biology,
chemistry and physics. If we shine white light on chlorophyll, its molecules will absorb certain colors of light. The light that isn’t absorbed is
reflected, which is what our eyes see.
A red apple appears red because the molecule of pigment in the apple’s skin absorbs blue light, not red. Thus, we see red. Chlorophyll molecules
absorb blue light and some red light. The other colors are reflected resulting in the green color that we associate with plants.
Plants get their energy to grow through a process called photosynthesis. Large numbers of chlorophyll molecules acts as the antenna that actually
harvest sunlight and start to convert it in to a useful form. Here’s where the absorbent properties of the chlorophyll molecule come into play.
It turns out that eons of evolutionary design have matched the absorbance of chlorophyll to the actual color of the sunlight that reaches the leaves.
Sunlight consists of primarily blue and red light mixed together, which are exactly the colors that chlorophyll molecules like to absorb. Light is a
form of energy, so the chlorophyll is able to harvest the sunlight with little waste.
