What if

1. If chinese were discovered the world before europeans, we would speak mandarin instead of spanish or english. Actually, mandarin would be the international language instead of english. I also think that they have a different culture that spanishs so maybe  all america would be one country. I also think that latin america would have less poor people because they would have developed really colonies through all america. Spanish only came to america to use the resources they did not develop any kind of economie there.
2. If two forms of highly intelligent life had evolved on earth, we would life in better condition.  These two forms of highly intelligent life would work together on Earth and they would put all their effort, intelligent and the best of them for better conditions, improving things that  do not have solution.
   I think that all the processes would be simples, the problems in the earth, illnesses and other things would be solved.  They would do different things to improve and ensure a better life for all.  They would use all their intelligent for it
