The sixth part of the equation is whether or not the life-forms have created detectable technology (radio waves, death stars etc..). The seventh part is how long they have had this technology for - if an alien civilisation 300 light years away only started broadcasting radio last Thursday we're not going to notice for a while.
Anyway, sorry to be pedantic, but it is an important distinction.
Over to somebody else then.

On to the next answer.
Hmmm....almost legendary thing? The God particle?
