This is a big question for me and i want to understand it scientifically.Human being needs oxygen to breath and its the main reason for existence of life , but , the question is can we make a new life by a new fundamental elements ?
There are theories, but the origin of life is not "known" by any stretch of the imagination. There have been many discussions about life forms existing, or being created, from elements in a different arrangement from our own. It's a great thought exercise but we are probably hundreds of years away from the technology and knowledge to get it done.
