To quote from a comment posted from here:

"I enjoyed the first linked article, (The American Scholar), it's fun to read, but I kept thinking about something Steven Hawkings once said about stuff like this, in effect he said, we can come up with all kinds of different ideas of space/time and reality, but if we can't test these ideas, poke them and demonstrate any cause and effect, then they are of no value to him and he can't waste his time with them."
So there are almost 7 billion versions of existence, just counting the
human species alone. Well, that certainly makes things easier, to say
nothing of even less trustworthy.
Hawkings comment summed it up for me.
