Ahh ... an interesting question! Thank you, Free_Style! I suppose that many people will agree that there are more than one thing or reason which are 'responsible' for the Mankind to sustain to stay alive .. to make it alive. Let me divide your question giving a few suggestions, depending on the different point of view. On one side: from scientific point of view (in general), Mankind and all creatures (on Earth) owe their existence to the proper correlation and proportion between nitrogen, oxygen, argon and also a little bit of water vapour, carbon dioxide, ozone, sulphuric dioxide and .. some other aerosols ... that are well known as air :-) .. and of course because of factors as fertile soil, Sun light, water, suitable temperature and diversity of species. All these things together make life on Earth possible ... for us .. (and maybe many other things btw... like chocolate, sport cars, new Gucci sunglasses and probably those delicious croissants I found in the new bakery near my office ;-) On the other side: as individuals all we need to develop ourselves in different directions in life, which includes different terms, conceptions like ambition, competition between people, our understanding about "what we are", "what we want to be" , “what we have to be” and "what we are able to be". All this refracts with our understanding for creating a family (something like to work for yourself and for others, and to feel great doing this at the same time), self-improvement (smtg. like to work for yourself mostly and to feel great doing this), career (smtg. like to work mostly for others and NOT to feel SO great doing this :-D ) ... our understanding for what is Good and what is Bad .. and Why :-) Ohh ... I lost myself in all this :-) But Free_Style, in my opinion the answer of your question is only one … i.e. God makes Mankind alive, because without Him nothing will be possible… and all that was mentioned above are just … details! :-)
