I'm also asking is it possible that another planets seeds have landed on our earth or CAN?

Basically i think its possible because space is a vacuum as well as being very very cold so i was thinking that would preserve the seed long enough to land on a planet and sprout creating the first life on another planet?

has this been asked?
