I don't think this has to do with aliens from the previous post which is for Adults Only but during my childhood I spoke with my mom about planets.

She said Venus has rain and that it's made of water. I looked up at the sky through the window. It was blue. I thought about it and said that if there's a lot of something, even something very small, like air, it will always make a color. I thought about colors when I was young. Earlier she made creme caramel which had too much sugar. Sugar is a clear color but it looked white to my strong eyes.

I asked her "If Venus is made of water how can it have rain? It would need to have clouds, it would need a place between the water and clouds for rain to fall. It's blue, like earth and the album cover of my favorite song which I heard in Bulgaria. It would have to have oxygen. Maybe our temperature readings are completely wrong, and we don't know almost anything about the planets around us. What temperature does Venus need to be for it to make clouds that fall as rain? If it's too cold there wouldn't be clouds. If it's too hot there wouldn't be rain in between their formation and rainfall. I don't think a planet entirely made of water would have gravity even though I don't know how space works." I was on the verge of saying something that would complete my theory, but my father had hit me so I was not able to say any more.

"If we were able to make a large body of hydrogen and look at it from a distance would we be able to see the color?"

"If we made a large amount of helium would we be able to see the color under sunlight?"

The only last thing I said after she explained why it's not possible to do this is "What if we looked at something that's small under a microscopic while somehow keeping it in an area with a machine that traps it and beams light at it. Would we be able to see its color?

We had talked about the periodic table of elements before, and this is what lead to this conversation. That and what she said about Venus. I was 3 years old I think.

The only other thing I said is that maybe Nasa has taken photos of earth, but each time the clouds have been in the wrong place, and maybe in time it would make a photo where our planet is made entirely of blue and white. A sphere.

The final thing I told my mother is "I think you're right that the rain on Venus is acidic, but maybe it's still growing, and in time that water will become neutral [ph.]" I added "What if it has land?"

Later on in school I learned that when water becomes a cloud it purifies the water of polluted things. Where is the acid going during the thousands of years that Venus' water becomes less acidic. Maybe it reaches the outside of the atmosphere at the top. Maybe it would form a ring?

Acidic water needs a different temperature to make clouds, but maybe as the acid leaves the atmosphere and forms a ring, Venus becomes the same temperature as earth?
