We always assume first alien contact will be meeting with some strange looking alien, maybe with a multitude of limbs, sometimes with none, etc. etc..
However, so many of our Science Fiction stories talk about humans having strange bodies that have been manipulated at their genes and have other enhancements like cyborgs. One book I recently read was about humans that had 8 limbs, all arms, they wanted that for their work in space. Or gills for living on water worlds...
Why is it we can think that humans will manipulate their bodies to such extremes but aliens will all be homogeneous monsters that "scare" us just because of their alienness. I have to wonder for first contact if they would have specially designed bodies made for their ambassadors to communicate with us. I would think it might even help understand our frames of reference etc.
So assuming benevolence on the part of our first visitors how far might they try to modify their appearance (at least a few intermediaries) to communicate with us?
(I had a similar question before but it was poorly done, trying again and hope this is better)
