I wrote the post. The context is clearly about scientific evidence because I begun by speaking about string theory:
A lack of evidence does not mean something does not exist. String theory, the theory of parallel universes or a multiverse are things I am not willing to dismiss though some scientists do. I don't need my wife to give me scientific evidence of her love for me or expect to find any evidence that my dog likes me. I believe in these things, but there is no evidence of things like "love" and my dog's appreciation for me.
Despite there being scientific evidence for either or not doesn't mean I don't believe in them or require scientific evidence of them to believe in them. People don't always accept things on the basis of evidence.
And you can't produce any kind of evidence or argument to prove either of those things anyway because my beloved died 7 years ago and my dog died last year.
