I suppose you could take the writers claims point by point and refute each one. But it seems to be one more of those cases where you can't win because the writer isn't going to admit to any of your points. If you did the writer would then claim that you were simply refusing to accept the obvious truth of his points.
Now I almost agree with the author about string theory. I have my doubts about it. But I don't think that his claims about it are necessarily anything close to true. "There’s many String Theory solutions that allow for other dimensional beings, an afterlife, and spirits existing, so if the String Theory is considered as science so should that String Theory solution." I'm not sure what string theory solutions he is looking at there. In fact I'm not sure that string theory addresses the question of life in any form. I was under the impression that it was mainly concerned with QM and GR. And neither of those directly addresses life.
