So you're saying your a realist and need evidence to support any beliefs you have? I think some type of spiritual belief is helpful and comforting, an example being karma, although as I said previously I'm unsure where I stand about it. I don't feel like I need concrete evidence to believe in things in life, take religion for an example. I'm not a religious person, but I do believe in some higher power and I haven't quite worked out why I even do so, the thoughts are just there.
I think evidence of the universe caring can be shown through people. Look at charity's helping people in developing countries for example.
