What do YOU personally believe is TRUE though there is no evidence or proof or facts to substantiate it?

You say LOVE? I say love can be faked. Anything can be faked and anyone can be tricked at any time for any reason. WHY?

Because people NEED to believe in the abstract somethings in life.

Truth
Honor
Justice
Love
Kindness

All of the above can be faked and have been and will continue to be. Lying and faking and deceiving is a favorite activity or profession for some. Why only they know.
