Have all species on Earth evolved from a common ancestor? Claim? And Evidence?

The UV radiations from sun reaches earth’s surface through the atmosphere. The earth’s surface absorbs some of the heat and emits the heat energy. This emitted heat energy is blocked by greenhouse gases.

explanation:

the sun shines white and black light to our planet. the white light has all the colors in it. in our upper atmosphere, we have dust particles and oxygen molecules. the white light meaning all of the colors in a rainbow shines through the upper levels of the atmopshere and the blue light scatters across the entire planet. that is why our sky is blue.
