How old are your siblings? If they are young enough, offer to read them the mythologies of different cultures. Kids like to be read to and would probably jump at the chance to spend time with their older sibling. Hell, I am 48 and I like to be read to also.
You can point out that the people who believed these myths believed them with as much fervor as your siblings do theirs but drop the subject after that. Be subtle and plant a few seeds. Read Genesis to them. The first book of the bible is crazy. You can let them know many Christians just consider the stories to be metaphors so it is okay to point out the nuttiness in them.
I would disagree slightly with AFTT. Until you leave home, be shy about expressing your opinion to your parents. You are dependent on them for food,shelter and decent treatment. Your parents might very well be wonderful people who would never try to pay you back for leaving their faith but the risk is too great for me to suggest that a young atheist not be very careful about stating their lack of believes.
