So like the title says, what do you think/know would remain the same for Aliens? Only premise is that we must assume they were evolved from cell division, meaning went from a primitive stage to either still primitive or advanced. Obviously math is the same, 2 + 2 will always = 4 no matter the language/planet you are on so this got me thinking... Pi would still be non terminating as well, and the wheel/ball would still be huge inventions. If a primitive life form had wheels and some sort of beast they tamed, would be logical for any being to make a cart. Do you think that would lead to combustible engines? Is combustion power inevitable??? What say you all? And what do you all think would still be common between us and aliens? Are we just prisoners of physics? And if so why would life evolve too much differently than you see here with all the 1000's of creatures we have here. You may say that is small minded to think, but could any of us imagined all the incredible life forms that have been discovered here on earth? Is it plausible to think of beings that fly? How would you explain that? Any "power/super power" you think they would have needs to have an explanation on how the evolution of it took place.
