Are the moon and the sun alive? In Soul Eater, the sun and the moon seem to have a face and sometimes laugh.
Are they alive or is it just their design?

The Sun and the Moon:
A somewhat theoretical answer:

Living things display the 7 characteristics of life - which are:


Movement 
Respiration 
Sensitivity 
Growth 
Reproduction 
Excretion 
Nutrition


They definetly exhibit movement and respiration


And they are sensitive to conditions of the atmosphere


They do not appear to grow, but this could be because they are adult.

They do not appear to reproduce.

They excrete light onto the world.

The moon may be eating something.



If the sun and moon's reproduction properties are anything like our own, which they are modelled off, they are non-existant. Stars and planets are formed - a non-biological formation without passing on any genetic information

This, combined with the fact that many of the other characteristics are assuming a lot, can bring us to the conclusion that they are not living,

Although, having said that, there are a couple rare articles around the web that claim stars are living. Example

So I guess you can justify it to be either true or false, whichever you would prefer :)
