Aliens are big headed green men with skinny arms and legs and a round belly. They live in outer space,and they have very large heads and very big eyes and mouths with little slits in there head for there nose.

Yes I think there might really be aliens.you never know what is out there .people say they see them.

I would think you would need a water saw for such a delicate thing, and use a very fine blade. I hope this will help.
