[i]Realistically[/i], I imagine organic lifeforms from other planets arw gonna be culturally and biologically similar to humans or our animals. If Earth was a 1 in ten gajillabillion chance it's more than likely other planets will just seem like off-shoot timelines rather than actual tentacle people with anal probes. Which means alcohol, religion, natural foods, etc, would be very similar. You could hand them a chilli pepper and say "Shit's spicy" and Gorthlafax Balthazar will be like "Oh fuck, you have gelefese here too?" What you're thinking of would be an entirely different universe entirely, where the rules are always different. X'ir'k'in'thro'phu'ck from the castchlobetch nebula will look at a pepper and say "WOLOLOLOLOLOLOLO IT'S GOT A FUCKING BOMB, GET THE FUCK DOWN." because X'ir'k'in is from another Earth where peppers fucking explode when you eat them.
