Comparing our evolution to another possible intelligent lifeform is quite ignorant. Our existence is but a blink in the eyes of the universe. Our 'knowledge' of the known universe is equivalent to a preschooler. People in general are quick to shun any possibility because they can only see our current limitations. Our progress is hindered by our own ignorance toward eachother. Could you actually imagine what we could accomplish if we actually worked together as one species and not in competition?
i understand what you're trying to say with the bolded but the comparison doesnt really make sense...a preschooler compared to what?
as for your last point...i'd say we work together more than we used to in certain situations
one function of human progress is globalization....of course with that we have a bunch of other crap like nuclear threats
but now especially in the space race we are looking more to collaborate than compete imo
the international space station is being built and worked on by a various amount of countries...
jobs,science, all of that isnt local anymore, or even national..its really for the world(or certain groups of countries)
ya you had trade in the past..but its so much different now than back then because it took weeks and months to travel and trade and now you can do it at the click of a button
lotta countries left in the cold though, but part of the issue is that they're not developed so they cant substantially contribute to,say, the international space station
