ANSWER: The language and intelligence of homo sapiens have progressed them a lot. Humans have learnt to pass on information in a more accurate manner. Had it been the earlier ages when paintings on caves used to be the only medium of communication and passing of information to generations, it would have been difficult to make understand the tough things and progress ahead. Humans have created their own culture based on their language as well which are then passed on to humans who use other languages and make a beautiful cultural exchange thus sharing experience as well.
