We may only think that because we evolved here and thus think you must need all of that as we can't think of it any other way.
On another note, you probably are absolutely right and we do need at least some of that. Not too hot or cold. No massive asteroids to destroy everything...etc. I think some of the rest may be negotiable though. Like do you need water? I think yes, buuut maybe some other liquid could work?
