you cannot back it up scientifically

quite true. But do yo have to? Major question science is supposed to answer, is "how?". It, by definition, is not supposed, and can not, answer question "why?"

If I put a little bit of this stuff into that stuff, it goes green. That is the essence of science in the long run. Why there is stuff at all (which scientist can experiment with) is philosophy, but not science.
