Then alas I have failed. It should show you that other options exist. I think a spaceship with viewing decks is ludicrous.
I already did, it is too small. You need to propel the thing, the need to feed the occupants, and if these are aliens are from a planet with gravity then they need some sort of gravity and workout to keep muscles in shape. It is just too small. In fact I think it is ridiculous to consider that a 35 foot ship can cross space. Honestly, all this tells me is that you have grasp on space itself.
I am not assuming that just we cannot do it. I know that space takes a long time to cross, and that ship is not built for long distance journeys, the description is an observation vehicle. It is not assuming we are the smartest, I do not have to be the smartest person on earth to know I will die if I stand in a volcano. Physics and practicality negate long distance Interstellar travel in such a small craft.
No, I just do not see ET, I see an exotic craft, you have made the leap that because the craft is exotic, and the described humans must be ET.
What specifically points at ET in Father Gills description, Can I ask you to outline the points please?
