Somewhere in the universe, there is a planet similar to the Earth, with living beings similar to humans:
- they can find on this planet any resources we can find on earth (water, clay, cooper, ...);
- they can do anything a human can do (move, handle objects, ...);
- (edit) they are biologically identical to humans.
I think* that there is a significant chance that this civilization build primitive weapons, hunts or boats, like we did before - just because their life may depend on it. ... and maybe later, they will also discover farming, agriculture, etc.
But I doubt that there is a significant chance that one day they will build an iPhone, because we didn't build this for survival.
That said, it must be a moment from where the alien technology should differ from ours. Which era?
