Nice question. Just the other day I was discussing this with friend. She does not believe in life after death and she said that people who believe in something bigger than us are just gullable. She meant that if there are things we cannot explain it’s just because science hasn’t found the answer yet. If, for instance, people born in the middle age suddenly saw something working with electricity, they would probably think this is a miracle, but today we know there is an explenation to this. The same with everything else in the world. So basically, yes, there are people who firmly believe science will one day find all the answers. I am personally not really sure, to be honest.
