What about the tides? Tide comes in, tide goes out. Never a miscommunication. Can't explain that.
"You should pay more attention in science class and maybe read a few science fiction novels while you're at it. In order for carbon based lifeforms (that's us, btw) to be able to live certain conditions must first be met. I won't mention most of it, as it would probably go right over your head, but the day/night cycle is important and needs to be similar to Earth's (otherwise plants get too much sunlight or too little and die off, and no oxygen is produced, and all higher lifeforms die). The length of the year would be comparable to ours, but would naturally have some variation."
Well, this is an interesting conversation. First of all, plants on earth have evolved according to earth's day/night cycle. If earth had a 36 hour day with 10 hours of dark, plants would have evolved in a way such that they could tolerate that system.
However, there ARE some conditions based on Earth's specific position, rotation, revolution, etc that are necessary for life as we know it. For one, our atmospheric temperature allows for water to be liquid most of the time. This is important for the development of life, as liquid water acts as a solvent for many chemicals, allowing them to form together in various compounds. Water itself has several unique properties, the way it's Hydrogen bonds cause it to act, etc, and I believe there's only one or two other compounds which could allow for earth-like life, or any life at all really.
