As far as attractiveness goes - that is so subjective that surely a grey worlder would think our people are beady eyed and weird looking. If they are gooey we would be dry and scaly, if they are dry we would be wet and gooey (by comparison)

It would be great if aliens were real. For some reason I don't think they are. At least not in the cartoon way where its a non human species that does similar things to humans but might have different rules and physical attributes. If there are aliens they might be truly alien to us, like for example how the trees on our planet are able to communicate with eachother and pass information to eachother. We think of them as large sticks in the ground but they might think of us as buzzy dangerous chopper downers.

So maybe in the universe there are aliens but if we were with them we wouldn't even notice them?

but its more fun if they are hot rodding around with cool ships and doing lots of cool stuff.
